What's the deal with gearboxes? Why don't more mountain bikes have them?

Today we'll look at the Zerode Taniwha, which features a 12 speed Pinion Gearbox. Gearboxes shift fast, require little maintenance, are protected inside a solid metal casing, and have all the advantages of a belt drive. Why don't we see more of them?
Today we'll talk about that.

They really make the most sense on e-bikes. That motor/gearbox combo Pinion released with electronic shifting is the ideal situation for this.

[@thescerigai]

not having a derailleur to smash off on a regular mtb doesnt make sense?

[@iboysven]

The only Problem left with these pinion mgu bike is that they start at 5500€😅 So the gearbox - motor combination most likely costs at least 2500€

[@SethsBikeHacks]

Although I have not tried Pinion's new electric drivetrain, it makes total sense. Gearboxes have already proven themselves on other motorized vehicles, and with how much abuse E-bike drivetrains deal with, it's a natural fit.

[@NikolaiVozza]

[@thescerigai]

[@drv_channel]

Another advantage on full-suspension bikes that I think was missed was that you are removing a lot of unsprung weight off the back wheel. Getting rid of the cassette and derailleur can make a huge difference in suspension performance by minimizing unsprung weight. I think gearboxes would make a lot of sense for downhill bikes where suspension performance supersedes all and weight doesn't matter as much. Also, this would be a great application for electronic shifting, get rid of the grip shift and just use a button shifter and solenoid or motor-based actuation.

[@someindividual7920]

For all interested how a dh bike with a gearbox looks, zerode has one ( i believe its called g3) and theres a swiss brand called gamux bikes

[@mikemanthe]

You make a great point! You could even design the ‘buttons’ to look and feel like traditional thumb paddle shifters to help ease the transition.

[@sp00n]

I've seen a couple of riders somehow losing their chain during a race run as well, this would (probably?) be eliminated with a belt drive as well. Although you can also use a gearbox with a chain instead of a belt.

[@mcarmstrong14]

Pinion recently released their Smart.Shift Gearbox which is electronic :)

[@sungear]

Mtb riders embraced 29 in wheels, bigger frames and low pressure tubeless tires. These things are heavier and have more rolling resistance than their older counterparts. It bugs me when people talk about efficiency and weight as drawbacks to gearboxes. They have already proven they will tolerate extra weight and rolling resistance if it has other advantages. Gearboxes are tons better in lots of ways. Cost is the only barrier.

[@adamweb]

You briefly mentioned it but yep, these are best suited for ultra endurance cyclists that do thousands of miles on crazy terrain. Ryan Van Duzer is a big belt drive fan.

Really surprised the topic of noise while descending was not mentioned. It's basically silent going downhill, all you hear is the trail chatter on your tyres. So so refreshing. Not to mention a massive reduction in weight off the rear hub with no cassette / derailleurs etc = rear suspension performance through the roof.

[@frankm9334]

i want a silent hub for this reason! the zerode is STUPID quite going down

I'm surprised he didn't mention how many times you smash the derailleurs system during the rides. I smashed three systems which cost in total over $2'000. You can't really enjoy the ride fully, worrying it may cost you a lot of money and time.

[@mircomuntener4643]

Makes for a much stronger wheel as well, with less hub flange offset.

[@brnzhut]

just curious how rear suspension performance better with light weight on rear wheel? the weight on rear wheel doesn't fall on the rear suspension tho.

[@PsychicDavidJames]

I'm one of these people with a pinion gearbox on my bike (priority 600) and I ride it because it works in all conditions, and deals with off-road and road riding equally well. I love the maintenance being minimal, and the lack of any real issues with having to deal with a chain.

[@Macks_Mustermann]

For about a month I have been riding a Rohloff speedhub in my commuter- and travel-bike and I must say, I love it! Sure some of the lower gears are a little bit noisy but you get used to it very quickly. For me the instantaneous shifts, low maintanance and durability are way more important than a silent drivetrain.

[@SethsBikeHacks]

Rohloff has been getting a lot of love in the comments, and I haven't tried one in close to a decade. I'd be interested in checking a newer one out!

[@tarstarkusz]

You are comparing apples and oranges. The Rohloff hub is 98% efficient (it is the most efficient internally geared hub). Also, it lives in your wheel and not your bottom bracket. Frankly Rohloff hubs are not for mountain bikes. But, also, this pinion box is a POS. I don't know why seth is shilling it other than greed. These things are really inefficient. 9 meshed gears plus windage losses because of the oil bath inside it. Where they may shine is cross country where conditions can be horrific. Pedaling through mud in a heavy downpour and other bad environments and where reliability is really, really important. But the Rohloff is already the king of this application. Where pinion really is bad is service. Just try getting it serviced in some small town in the middle of the back country in Mexico or something. You could be off the road for weeks waiting for replacement parts.

[@rff999]

I disagree... I love my Rohloff MTB and it works well! Been running it for 2.5 years now

[@victorrguez1405]

I have a Rohloff hub on a surly pugsley. I love that thing just from how different it is compared to my other bikes.

[@maddox0110]

After destroying 2 Alfine 11's in 1 year, I went Rolhoff. 2 years later, I'm still riding my obese recumbent tadpool with a BIG grin, and the second oil change coming up.

[@TheOutsidePerks]

Worth mentioning, from a touring bike perspective, the Pinion's even spacing between gears makes it easy to keep an even pedaling cadence over rolling terrain. Also with no derailleur protruding, and no oil covered chain, it's easier to load bike into cars, buses, hotel rooms etc.

[@exothermal.sprocket]

@enriqueamaya3883 Where is he? If he's in Heaven, it's a little hard to follow because I'm on earth. Explain.

[@aruppert314]

Also one of my favorite features of the pinion gearbox is the ability at the bottom of a hill to switch it to its first gear and instantly get up the hell without having to move around first and change gears on the go. Especially useful in traffic when you stop at a red light at the beginning of or in the middle of an uphill climb!

[@someindividual7920]

Well said

[@aboutthearthur]

Also useful when mountain biking and failing to drop enough gears and having to put a foot down. Being able to drop into 1st and start pedaling rather than having to hike-a-bike to a flat spot is really nice for those of us who suck at mountain biking.

[@ImpactWench]

But that's not how you go up a hill unless you're on an ebike. You start out quick, but gradually slow down when going up the slope. You *want* to shift on the go, under load, to keep your cadence constant.

[@M.F.Hafizhan]

Just shift down before a climb if that's a concern? Well tuned derailleurs shift quickly anyway

[@edwardhook8173]

I recently bought a Zerode Taniwha a few months back and i absolutely love it. Effectively zero maintenance and super reliable. Efficiency is hardly noticeable. Best thing i’ve ever bought and i could never go back to a conventional drive chain, especially since conditions here in the UK are regularly wet and gritty, wearing out chains and derailleurs super quickly. It is just so much better 😂😂

Cybro No.5 & No.6 from Cybro Industries in Bassano Del Grappa, Italy also use the Pinion C1.12 with Gates Carbon Drive belts. Both are fantastic to ride. Like everything different they take a little time to adjust to the way they shift. Once you get the hang of it you probably wouldn't go back. Hint, the Gates belts do break, so carry a spare. We broke one on a Cybro No.7 and didn't have a spare - that was the end of that ride for the day on that bike, lesson learnt.

[@tri-seeker2753]

Thank you for this video, I was waiting for it from you for years 🙂 Being one of those gearbox enthusiasts, I have one thing to add: efficiency is not that bad as it may sound from your vid, difference betweens factory fresh piece and meshed in one is significant. Also that efficiency stays there no matter what, so if you have well maintained, clean deraileur, you can beat gearbox. Once you start clogging it with mud or whatever, conventional system starts taking a nosedive, while gearbox is still as "ineficient" as it was in the begining. So yeah, enduro, MTBO, commuters, long distance travellers... You should really try it in a long term, because that is where it shines the best...

[@HighlanderNorth1]

✔️ He's right in what ^he said in the first 5 secs of this video, about the big companies who wield major influence over the bicycle component industry. As far back as the 1950s, President Eisenhower warned Americans about 3 big industries that threatened the health and well being of our international society. He warned about: 1). The military industrial complex 2). Big tobacco 3). Big derailleur. Ike was way ahead of the curve on that last one! 😁

[@termitreter6545]

Tbh at least with the ~8-11 gear boxes that are often used on city bikes today, I found they have palpable resistance, especially at low speed. My slightly cheaper bike with derailleuer has less resistance on high and low gears. Although the bikes in the video are on the extreme end, so idk if thats really comparable.

[@infinitebirch]

I got a Priority 600 with pinion c1.12, hydro disks, belt drive, and dyno hub. Some of the components are pretty cheap but it's been completely reliable, which is what I was going for on a commuter bike. It lives outside through all seasons. I do definitely feel the friction a bit but it's worth it for casually getting around. The gear range is insane

[@aboutthearthur]

Love my 600 as well. The components that are "cheap" aren't bad by any means. They're just not luxury. They chose totally competent but affordable parts for everything they could to be able to afford Pinion at $2500.

@@aboutthearthur i totally agree. i'll upgrade over time as things wear out. my lights recently stopped working so i'll move to some better ones (or a better dynohub if that's what failed... i haven't checked yet). they made really smart choices to hit the price point, and i'm really grateful that they made it possible to afford

@@twillyspanksyourcakes Just because an internal gear setup isn't as prone to failure doesn't mean they can't fail. The thing about a derailleur setup is I can bodge it to get myself home if I don't have the necessary tools and spare parts to repair it properly. If I'm really concerned about long distances in remote areas where I'm concerned about failure, I'll just use friction shifters and an 8 speed chain and cassette. I work as a bike mechanic, I've seen internal geared hubs and belt drives fail quite catastrophically, and there's absolutely no workaround except walking. Customers are also furious when their "durable" setup costs them several times more to repair, especially if it's failed much sooner than the marketing guys would have them believe its good for.

No chance of road side repairs though, but I think it partly depends on where you are riding though. Even the perfect system fails, after it fails my priority would be to get back on the road.

I have one for commuting, all day, every day, every weather (try salted snow slush with your deraileur, and a couple of freez/thaw cycles). To keep the efficiency advantage of a derraileur you need to do a lot of maintencance.

[@yard2380]

Great to see Pinion mentioned on this channel! :) I don't maintain my bikes. I suck at doing that, that is the main reason I ride Pinion since 2012. Currently on my 4th Pinion bike (all Nicolai's) this one with a C 1.12 box. (612% range out of my head.) 1.18 is available, same range, smoother ratio. It is indeed 0 maintenance also in bad bad winter weather. (Rain, snow, mud, salty roads, etc, I don't have a car, so I always commute on this as well.) Just inject fresh oil once a year, or roughly once a year. I once did no oil change for 2 years, because it is "maintenance", but no problems. :) The grip shift they use is now quite outdated, later this year they will release the electronic shifter for the general public. For my riding style it has very little drawbacks. If I have to mention 2: You indeed loose a percentage of the power that is put into it, especially on the higher gears. (I would say 5% average compared to a perfectly new and fresh chain+cassette setup.) I never was able to feel that loss on a full suspension bike, but now that I ride a hardtail, I start to notice it a tiny bit when I put over 330 watts in it, but that is seldom. (But we are nowhere near early Nexus hub levels of loss, or the spongy feeling that gives.) A second issue: in a 12 speed box there is 1 point where you can't shift under load, I think somewhere between 8 and 9 in gears. I have that habit of "clutching" during my shift because of this. I never know when that gear is going to come along. That manual clutching I do now, (0,5 sec off the power) will be done by the electronic shifter in the newer, upcoming box. (probably in a matter of milliseconds, and you can stay on the power.) I don't care about the weight, but the system is in total about 700 grams heavier than XX1. It is heavy, but the weight is in the right place, with very little unsprung mass, a plus for a fully. All in all, very reliable. I ride about 6000km a year without issues, and without maintenance. Yes pricey, but worth it, and I don't own a car, so that money has to be wasted somewhere. :D Oh one last thing: the silence of this drive, especially with belt is something else, it is swooshy, but never grindy so to speak. :)

One thing to note of efficiencies, the timing belt actually has nearly the same efficiency as a roller chain, its the gearbox which is the primary cause for the difference in overall efficiency of the system

[@exothermal.sprocket]

The consistency of the gearbox would bring the efficiency comparison closer, because derailleur and chain systems are all over the place in their efficiency numbers with a host of non-consistent factors. The average comparison between the two makes this more of an emotional debate than anything anyone would actually worry about. It's like the people who obsess over a few grams difference in weight, when they could lose 5 pounds of body fat to start with.

For free riding, when you start going high altitude, this thing is fire. All the times i broke a derailleur by hitting rocks could’ve been avoid with this.

I have ridden them on several different bikes including the Cybro No.5 and No.6 from Cybro Industries in Italy. Yes they are a little heavier, shifting feel different, but they are unreal. I'm from Australia and they are rare to see however 18 months ago I ran into a rider on the Yack Tracks at Yackandandah, Victoria Australia (which is not exactly in a city) riding with a Pinion - I think he was using a C1.6 or C1.9 and he loved it - also he was quick both up and down some pretty steep hills on the Yack Tracks.

[@andrewparley6850]

They also argue that by moving the mass of the cluster off the rear wheel and into, the centre allows improved suspension design. The pinion gearbox motor + electronic shifting looks exciting!

[@rff999]

I have heard the argument, but I can empirically tell you is that my FS bike with a Rohloff rear has really good suspension performance.

[@exothermal.sprocket]

Depending on gear selected with today's derailleur systems, the effective chain pull angles on rear suspension is chaining between pro-squat and anti-squat geometry. With a belt drive, it never changes no matter the gear.

I think the biggest reason they aren’t as common is because they need a compatible frame to work with and those same frames are not compatible with traditional bottom brackets either. It’s less about upgrading your drivetrain and more about getting an entirely new bike. I’m sure established bike manufacturers have a harder time adapting to pinion because they don’t want to invest all the money into retooling their frame production to accept the gearbox and selling the bike for $1600 more than it would with a traditional derailleur.

[@aboutthearthur]

Totally agree with this. I now have two Pinion bikes, but that's only because I wanted specific full-bike upgrades for specific purposes (touring and bikepacking) and made the decision to select a pair of Priority bikes. Since you have to buy the whole thing as a purpose-built package, it's not like I could have "upgraded" to a Pinion setup on the Trek and Fuji I had beforehand.

[@FiddleSticks800]

They aren’t adopted because of 1) inefficiency, 2) cost, 3) compatibility, in that order. Why would I pay more for a bike that is sluggish? I have played around with one, the added drag is very noticiable.

[@hjacobsen9306]

I'm yet to hear the efficiency numbers but I know the old planetary gear hubs had a pretty low efficiency. Around town the old Raleigh's I used to ride daily did a great job. Wondering how much Pinion has been able to improve efficiency? Seems like it would be geared more towards everyday riders rather than race types(except DH?) given the need for maximum efficiency over convenience and ease of maintenance. Also the other potential benefit of a gearbox is a stronger rear wheel as all the dish for a cassette is no longer needed so even spoke tension in addition to instant shifting could be a real boon to the DH set.

[@michaelgeisert289]

I do not find the Pinion sluggish at all!! Definitely better than my Alfine 8 bike. And no chain lube needed.

[@acidrums4]

I mean, they'd do it in no time if they wish. They did for disc brakes which required different designs and considering different fatigue points in both the frame AND the fork vs. rim brake bicycles.

[@DJ-Daz]

I asked a couple of local bike shops what they thought of these, both said they are sweet, fairly easy to install, incredible to use. But, they both agreed, if and when they do go wrong, they are very difficult to repair. Not impossible, but it's going to be expensive because they take a lot of time. Maybe that's their lack of experience with them, if we all had them, they'd be far easier, as there'd be a lot of information on how to do it. But the entry fee here in the UK is around £2,500 plus fitting and setup. Should you get a great gearbox, it should last decades with only an oil change every year and new cables as and when. Of course, should get a lemon... But don't Dutch bikes have them? Or at least a lot more of them?

[@Bozza36]

The Pinion MGU already makes so much sense for e-MTB's from reliability, to unsprung weight off of the rear wheel (and only adds a few hundred grams over a regular drivetrain). Once they make a gearbox within a few hundred grams of a regular analog-MTB's drivetrain and very efficient, they will soon take over. Not to mention, there would be a massive benefit in terms of pedalling by taking a heavy cassette off of the rear wheel.

It worked great, snapped a belt after a few months use, had to replace it and because it was not expected by anyone that a belt would break, atleast not so fast, the process was hell. The stores did not have the proper tools or parts to do it inhouse (as promised they would be able to do) so I had to make a yank as hell solution. When they recalled the bike for whatever reason (cant remember) I got it back to them, insurance etc etc if I fell using it. But the beltdrive and shifter felt awesome!

[@sandymcarthur]

I offered to let you test my Zerode weeks back but heard nothing. Glad to see you put out a video on them.

[@namdarbolour9890]

Just a minor technicality, the Pinion does not use planetary gears, rather conventional gears on 2 shafts side-by-side like a manual transmission in a car. In addition, in the 12-speed model, it has two stages, not one as cars do, meaning 4 speeds in the first stage are fed to 3 speeds in the second, multiplying like front and rear derailleurs. A very well-presented, unbiased, and balanced review. Not your typical fanboy stuff, ha ha! Thank you. PS: A mini planetary gearset is used for shifting only, I believe. It is not part of the powertrain. It's the one you see when you take the round cap off the side where the shifter cables enter.

[@klauswolfsberger5793]

Hi, I own a Zerode taniwha enduro since a few weeks. Yes, the pinion gesrbox has at the beginning some noticeable drag, but it wears in and after a few rides with serious climbing the drag is way lower. I also was skeptical about the grip shift, btw Instinctiv bikes offers a trigger shifter for their pinion bikes, but know I think, after getting used to it, it is the best way to go. Cheers

[@edwardhook8173]

recently bought a zerode too, best thing ever, could never switch back to a normal drive chain

[@exothermal.sprocket]

Is there anything about an early oil change in the owner's manual, to flush out any metallic debris from the meshing of gear sets when they wear together? All manufactured gears in transmissions have machining variances on gear teeth that will bed to other mating gears, and shed microscopic bits of metal initially, and smooth out with a bit of use.

[@danielm593]

Every single vid from Seth is entertaining or informative. This gearbox looks awesome, but with that grip shifter, don’t you find yourself having to adjust your grip with every shift? 🤔

[@Skawagon]

As far as I understand it the gripshift is said to be neccesary as the gearshifting mechanism need strong pull in each direction in order to change gear. It would be cool if they could engineer around this problem, perhaps they will in the future.

[@SimonBauer7]

​@@Skawagonyou should be able to engineer a trigger shifter to do that, or go electronic.

[@sandymcarthur]

​@@SimonBauer7I've seen the is at least one out there, but it's spring based for the second cable. Haven't tried it, but seems it means you do 2x the work to up shift so it can down shift for you.

[@yard2380]

Yes, I sometimes find this annoying, but only under very specific circumstances. A company called Cinq makes a trigger shifter (left and right paddle) for Pinion (C-line) It is too expensive for me. The upcoming electronic shifter (and proprietary updated Pinion box) will finally get rid of the twister. :)

[@Skawagon]

@@SimonBauer7 I suppose isom sort of trigger shifter will be done eventually. As fot the wireless - as Seth mentioned the gerabox is well suted to the most extreme conditions - Like a guy pedaling over Gobi desert. In those conditons I guess the simple soliution wins over and is a one thing less to take care of. With that being said, I still belive it could go a long way to spread the apeal od gearbox drivetrain.

[@dougfromsoanierana]

I’ve ridden many miles on bikes with Alfine and Rohloff hubs and one advantage not mentioned in the ability to shift multiple gears while stopped or very quickly go through a bunch of gears quickly. That kinda changed how I ride in the city. For not a ton of money you can get a new Alfine 11-speed hub and adapt it to many bikes, old and new. And the trigger shifter is great.

I'm surprised that you didn't mention hub gears, where the gearbox is shoved in the rear hub. They're somewhat common on commuter bikes where I live, where the (unmentioned) advantage of shifting whilst stationary is quite useful

[@geepeerces]

they add unsprung weight to the rear wheel, which impacts the effectiveness of th rear suspension, I'm sure I heard that mentioned in the video. I'd love hub gearing with a belt for my middrive commuter/urban ebike which currently is a Shimano 9-speed with a Shimano middrive

[@Rubardock]

I suggest looking into the hubs of Rohloff. They replace your back hub with a gearbox, so you won't need a six bolt frame

[@neurokinetik]

Yup. Has most of the same advantages and drawbacks of the pinion system, and can be setup to use either a chain or belt.

[@drv_channel]

Would be terrible on a FS bike though... all that extra unsprung mass...

[@ianferch7970]

This was the bike I wanted to buy 3 years ago but 29er sizes were too large. Then I discovered the Instinctiv brand and took delivery of a M9 last year. It can be ordered with a tigger shifter another advantage of a gearbox bike is the rear wheel isn’t dished. It’s probably stronger than the front wheel. My bike is modified with a Pinion rear spider equipped with a 36 tooth narrow wide chainring. The first gear is super low and the frame holds 2 water bottles. The perfect bike for an old guy in British Columbia and I get constantly asked if it’s an e-bike.

[@AndrewBull-uq7ui]

Hi, along with a rapidly growing number of people I ride this bike. I bought it to replace my 2022 Slash 9.8 and the difference is unbelievable - in a very positive way. The enduro Taniwha is a mixed wheel long travel bike and it just eats up anything you ride it on. Yes, there's a bit of drag while pedaling, but the benefits of silence, lower unsprung weight and centered mass far outweigh the disbenefit if you're happy to take a chilled approach to climbing (or a chairlift!). Coming in June is my G3, which is the DH version of the bike, as raced by Sam Blenkinsop in the UCI World Cup this season. The G3 is next level (having ridden a demo earlier in the year) and I can't wait to start racing it. Plus, its great to support a home grown bike brand that's slowly but surely taking on the world. Thanks Seth!

[@agrmbl]

You definitely feel a bit of efficiency loss. Although it’s probably less than a dirty derailleur (i.e. after 15 minutes on trail). And it’s supposed to break in after 500km or so, would become much smoother.

[@SethsBikeHacks]

This is an interesting point a lot of people have brought up. When a derailleur gets all mucked up and dirty on a long ride, it too loses efficiency while the gearbox remains constant. Depending on the nature of your ride, a gearbox could be equally as efficient and cause you fewer issues.

[@streddaz]

@@SethsBikeHacks the derailleur system is also less efficient at either end of the cassette due to cross chaining. Add some mud and grit and they would be pretty similar.

[@exothermal.sprocket]

Just like a car or motorcycle transmission, they have a wear-in time where the meshing teeth lose their tiny machining variances and smooth out, reducing friction and reducing noise. An oil change would be advisable to remove the tiny flecks of metal probably, and thereafter, good to go.

[@agrmbl]

@@SethsBikeHacks long-term review incoming: So it’s 8 month later and 3K kilometers, mostly gravel and bikepacking-like tours in Cyprus mountains. Gearbox became buttery smooth long ago, had yet to have any issue at all. In total I can remember like three times the gear skipping (for a quarter of a turn) probably due to very unlucky shift and very hard pedalling. No maintenance, no nothing, just wash the bike once in a while. Several times went through clay after the rain, bike got unbelievably dirty, no issues with the belt drive. Due to change the oil soon (kit is like 20 euro or something), which is a very straightforward operation. Also got spare belt, just to be sure on them extended mountain trips (not expecting current one to break, but new belt is not that expensive and weights nothing). I’ve got 12-speed version (with 600% range), which means that 1st gear is waaaay to low to move (steepest climbs are like 3rd gear for me), but the 12th is OK for pedalling for up to about 40km/h with my gearing - which is road bike territory. Al in all - it’s a dream come true. Would surely recommend.

[@trulsdirio]

If I had the money I would be riding a Rohloff, recently had one in the store that was shipped to Rohloff for a full overhaul, it did over 50000 kilometres so far and still is going strong. The inspection log had one oil change every year on it for the last eleven years and this was the first time it went back to Rohloff according to the documentation provided. On the efficiency statistics, regular drive-trains are almost always stated in perfect conditions, so no dirt or wear what so ever. Not really realistic out on the trail where the only time your chain is clean is in the garage after it was just washed. So they are closer together, tho there still is a difference for sure. But one you will only notice if you race I guess.

[@SethsBikeHacks]

I got to try a Rohloff about 7 years ago, and am curious how far they have come. I remember it being really compact, and it was on a pretty normal looking bike. That could be another cool thing to look into.

[@frostsmoke]

Rohloff Speedhub is great, I have one on my hardtail and I love it. Not ideal for a full suspension bike though (high unsprung mass).

[@trulsdirio]

@@SethsBikeHacks they are just regular gear hubs that fit pretty much every normal bike. They also have the grip shift with two cables but offer electronic shifting with Bosch or Panasonic ebikes. The hub itself is pretty much the same with only iterative changes over the years. Still expensive at a thousand bucks, but at least works with normal frames. Great range of over 520% (more than a 10-51 tooth!) with 14 gears. There are multiple ones doing 100000 kilometres so longevity really is there too. But you still have a weight penalty but efficiency is around 4% better than Pinion.

My 11 speed Shimano was $400 its on my commuter bike and has trigger change. It is DEAD silent and never misses a beat. The rattling dirty derailleur cassette dropped the chain at the worst time, oily black hands at the start of a working day even after scrubbing left black finger nail edges.I was all too aware that one chain fail crossing a busy road would be hospital or death. A great advantage is sequential shifting, trigger up 10 times or thumb down using every gear in order simply, Try working out the crazy shifting to do that on a bike with a front derailleur! I have had this for two and a half years I travel 34km a day to work and back and so far maintenance is a hose down after rain and oil once in two and a half years...

[@aruppert314]

Glad you got to try that bike and to comment on the pinion gear box! I’ve been riding the Priority 600 for several years now and I absolutely love it. I think it’s perfectly suited for touring and commuting, but I’m not sure about how well it would work on a mountain bike. I know the same company makes the Priority 600 X which Ryan Van Duzer helped design to be their gear box hardtail. It looks pretty sweet but is well out of my price range. The Priority 600 really is my favorite bike but it’s expensive enough that I would prefer to beat up a much cheaper bike out on the trail.

[@marcschlegel713]

Happy Pinion customer since 2012 here. I own a Nicolai Enduro bike with the first Pinion series P18. This one still uses a chain instead of a belt. I've changed the oil after 9 years and not because there was something wrong, just because I thought it is about time. The biggest issue most people probably have is the grip shift, but for the gearbox this is actually really great ( I hated GS on normal derailers). When something comes up on the trail you just remove the pressure on the pedals for a fraction of a second and shift multiple gears at once and after that you know the gear is in and you pedals as hard as you want. The other thing holding this tech back is bike compatibility. In my local group people switch bikes every 3-5 years (I am still happy after 11). The price is actually not that valid. This is a high end product so your have to compare this to this fancy SRAM line. I am considering getting a new bike in 1-2 years, but mainly because I am still on 26 and after some tests on our local trails 29 seems to have an edge (also replacement parts for 26 are limited). I probably will get another Pinion but with belt this time.

[@JimS870]

I was big into cars much before I got into cycling. My 5.0 V8 engine has a timing chain that lasts so long that I cannot find any instance of somebody needing to replace it because of wear. Timing chains in cars last much longer than timing belts, which are regarded as more fragile and in need of replacing at certain intervals. Imagine my surprise when I got into cycling and learned that the rubber belts were longer lasting than the steel chains, lol.

[@gman6059]

That's a really good assessment of the transmission. The pause needed to shift gears seemed way more intrusive than you made it out to be Belt drives are perfect for single speeds due to their quiet, simple, and reliable nature. The only issue is if you want to change gearing. You would need a whole new belt/cog combo.

[@SethsBikeHacks]

🤤belt drive single speed....

[@infinitebirch]

The shifting definitely takes getting used to, to me that's the biggest downside. That plus the extra drag. It actually reminds me more of driving a manual pickup truck than a smooth automatic car. I use mine for commuting mostly, for that's it's perfect

[@matthewvale4545]

The drag gets less and less as the gearbox wears in from what I've read. Its criminal how much sram expects you to pay for a high end cassette which is a consumable component

[@streddaz]

@@infinitebirchthe drag is actually less than you think. The best possible conventional chain drive (a single speed) is about 97% efficient. The Pinion gearbox is 90.5% efficient. The thing is, a 1X 12 speed drivetrain is most efficient in the midday gears and is close to the Pinion on the outer gears, due to the added friction of cross chaining. The 1X drivetrain is as efficient as 96.0% and as inefficient as 92.4%. On average it’s 95.1% efficient.

[@infinitebirch]

@@streddaz I've only ridden the priority 600, it also has very wide tires which I'm not used to. I'm wondering how much I'm feeling is huge heavy wheels and relatively budget hubs vs the gearbox itself. I'll have to try a more high end pinion bike at some point. One thing I can say for sure is the more I ride it the less drag I feel, but on group rides with people on road/cross bikes I have a pretty hard time keeping pace.

I'm not breaking chains, bending derailleurs, cleaning and greasing chains, adjusting cables, yada-yada. I ride, not fix my bike. I agree it's not the right option for racing. I'm a touring nerd, so I want to be able to ride for days on end and never worry about the drivetrain. Expensive yes- but if you haven't tried it, don't knock it.

Personally, I'm sold on gearbox transmissions. Lower maintenance, less likelihood of breaking a derailleur, or bending a derailleur hanger, plus a wider range of gears. What's not to like? I recently had a Rohloff 14-speed transmission installed for a 2nd bike. This time my trusty Specialized S-Works Turbo Levo received a Rohloff upgrade. Gotta say it is sweet. With a wider range of gears, I can now climb pretty much everywhere, I am loving it. I'm now enjoying the uphill flow every time I ride. This thing just performs perfectly. If you are considering a gearbox, just do it.

[@KlintonSilvey]

It also helps suspension performance as the belt tension is set without the need for constant derailleur tension

The transmission losses are higher than for DR bikes, but if you are not doing XC, gravel or road racing then a gearbox bike makes a lot of sense. Belt drives require a splitable rear triangle.

[@kuchenblechmafiagmbh1381]

I'm leasing a trekking bike by Gudereit since August of 2023 (wanted some gravel first) with such a C1.12 and it's great for commuting, we only have some hills here (however a couple of mountains just 30 miles south) and I mostly use gears 4-10, 11 and 12 only if I'm really fast/downhill. My dad said one of his work colleagues got a similar trekking bike since the early 2010s (so when Pinion was brand new) and it still runs fine. I would like to add some things: the C1.12 and the other C-Series have magnesium cases while the P-Series use heavier aluminium; the C1.12 has a total transmission range of 600% and every step is +/-50% (it's a little odd in the beginning, it often rapidly shift up my derailleurs when accelerating, two/three gears at once, here you rather shift up single steps and rather don't skip gears), so you're shifting linear, the P1.18 even got 636% in 18 steps so each shift is +/-35.3%. There's also another German bicycle transmission: The Rohloff Speedhub 500/14, this is around since 1998 and also has its niche (but they achieved 400k built/sold in 2023), cost you over a thousand bucks and is a heavy unsprung weight, but it's extremely reliable, the record holder has reached 384.400 kilometres in 2019 - the distance from earth to moon. As the name suggests is has 14 steps and a range of a little over 500%. IMHO it's worth mentioning that both of these usually have grip shifters with two wires and that's because the indexing isn't in done by the shifter like on derailleurs or other hubs but the gearbox itself and the Pinion simply doesn't shift, if you're too hard on the pedals (you can't turn the grip), it's a nice overload protection and thanks to muscle memory you'll automatically relief the pressure on the pedals when attempting to shift in a few weeks. Maybe I'll give mine some winter tires for upcoming winter season (or my cheapo Pegasus it's literally my spare bike now, I use it to get to the main station and lock it on there (and go by train without the bike) or if I go drinking/partying, it wouldn't bother me too much if that would get stolen), it's also perfect for that due to its encapsulation.

Pinion just unveiled its new Smart Shift electronic trigger shifter, so those who hate grip shift have an alternative.

I've been riding the Priority 600X for about six months and love it for bikepacking/rugged touring. I'm not completely giving up on derailleurs though. I will probably continue to use a lighter bike with derailleur so that I can actually keep up with others on single-day gravel rides.

Belt drives and gear hubs or boxes are awesome!

Yes, it weighs quite a bit and the grip shift is not the most ergonomic shifter you can get, but drivetrain maintenance is cut down to a 5 min oil change a year. For winter riding or commuting it's a no brainer.

A very nicely balanced and informative video. I especially liked learning a new expression, "Big Derailleur". Subscribed. There are obviously good arguments for and against both systems.

I suppose that some people change it from time to time, but for the most part, the oil in a manual transmission and differential housing (AKA: "rearend") is in there for the life of the vehicle (they merely get topped off if they are low, not an oil change), and those gears are under much greater stresses/loads than the gears in a bicycle gearbox will ever see.

The belt is the thing i want the most, as someone who rides in the UK i spend so much time maintaining my drivetrain because it's covered in mud 9 months out of the year, it would be so nice to just be able to hose off my bike and be done.
