High vs Low POE HUBS Worth It? i9 Hydra vs DT Swiss 240EXP/ 350

[@MortenProm]

Greate video. I'm into low POE. I've gone all the way with Onyx. 0 degree engagement and completely silent :)

[@andrewscasualmtb]

I'm looking into the Onyx. I'm reading about pedal kickback on these things, do you really notice it? The biggest drops I go off of are about 3 feet but there are a lot of rocks on certain trails where I live.

[@LaurentiusTriarius]

​@@andrewscasualmtbit depends on your suspension design, most modern full suspension won't be affected by it.

[@LaurentiusTriarius]

Onyx are good hubs but they tend to slip if you're pushing hard. I had a vesper in the back on my cromo hardtail for about two seasons (8 months) and it was slipping a lot. I could service the clutch but back to DT with a 60t ratchet on all my bikes, mostly for practical reasons and ease of maintenance...

[@andrewscasualmtb]

@@LaurentiusTriarius I ended up getting the onyx vesper and have been extremely happy with it. I haven't noticed any kickback at all on my bike and the silence is the best thing ever. 👍👍

[@50centHotDog]

@@andrewscasualmtbpedal kick comes from the suspension design. Different hubs “hide” the kick differently, usually related to their POE. Onyx are a bit different. The clutch “resets” after every engagement and the sprag clutch has a small amount of flex so it will absorb pedal kick a bit better than other super high Poe hubs. They recommend vespers for lighter riders. Most full size dudes run the classic.

[@db_cooper3941]

That loud POE sound freaked out security guard at my work one evening when I was rolling my bike down the hallway. He was convinced I was walking up to his outpost firing off a taser. I want to try the onyx hub too for the silent trail experience but $$$$.

[@gunny6517]

Great Review & Explanation…. When I upgraded my wheel set to Bontrager LineComp 40’s (Trek 2021 Roscoe 6), I also upgraded the hub to 108T, which made a HUGE difference for me and I don’t foresee “ME” needing anything better.. 🇺🇸

[@hansonwang2121]

Good stuff! I came from a 108 POE hub to a 75 POE hub and do in fact notice a difference when riding. I’m sure in a few months I’ll get use to it, but I am really tempted to get another 100 or above POE hub I’m just so use to near instant engagement.

[@andymtb5714]

I upgraded my Trek Fuel EX from 54T to 108T and absolutely love it. Never looked back. It sounds great, but I've also noticed how much better it feels. There's none of that "lag" between cranks, and it makes for smoother engagement. For $27, it was 100% worth it for me. Not sure about 690 POE, but hey I like loud and quick hubs.

[@juffkasvennsson4609]

May i ask where you got the 108 teeth cogs for the dtswiss hub? I thought dtswiss only does 54

[@andymtb5714]

@juffkasvennsson4609 you would be correct, DT Swiss does only 54T I believe. The hub I have and that I was referring to is the Bontrager rapid drive hub, stock with most Trek bikes. You can upgrade it from 54T to 108T with Bontrager's upgrade pawls and springs.

[@marcandrecoutu4798]

I find I prefer the feel of instant engagement on my Hydra hubs, but can't say that it's helped my climbing game. We are in the realm of diminishing returns here... I'd say the same for my carbon hoops.

[@lazylearner967]

When I first put on my carbon hoops, they felt more snappy to me. Pumping out the the corners seemed to really accelerate compared to my OEM hoops. (that feeling might have all been from my head to justify the expense) But most "upgrades" are for one's ego, not for better riding or faster lap times.

[@carpedownhillem]

[@mikaeloja7060]

I have the DT 350 Hub with 54 tooth ratchet. I have tried the 36 tooth aswell but I ended up going with the tighter engagement. Love your videos man 👌🏻

[@Phlizz]

It’s important to understand that there is unlikely any pedal kickback while you’re riding, the backwheel is rotating forward allowing the cassette to rotate as well without resistance to counteract the the impulse on the cranks by chain growth. Only on harsh low speed impacts the amount of chain growth would be to high with to little distance for the cassette to move and it would engage eventually causing a force on the cranks that is noticeable. What most riders mistake for pedal kickback is the uncontrolled movement of the chain in harsh terrain. The, often counteracting, wave like movements of the chain cause all kind forces to disturb ride feel and suspension performance. I found this discussed in detail by a Trek suspension engineer. Actually all full suspension bikes would benefit from a chain guide keeping the chain as controlled as possible. unfortunately chain guides are mainly associated with the purpose to hold the chain on the sprockets and futher with DH or freeriding.

[@piciu256]

I totally agree, tested it myself, swapped my 51t steel cassette for a single cog and I've eliminatet pretty much all the pedal feedback, chain itself still rattled around obv, however, it could spin the freewheel as it pleased without all that inertia, I'm gonna see how much difference STFU makes in that regard, cause swapping to a singlespeed is not something I want to bother with often.

[@Phlizz]

@@piciu256 👍Im also thinking about getting STFU. There is a cool video showing the difference (camera mounted on drop out showing the chain).

@@EnglertRacing96 agreed! It’s a real thing. DH/park on long travel bikes has it’s own requirements. There’s a reason for freewheel cranksets and „no-sprocket-gear“ on a cassette.

[@ThunderStruckMTB]

For me, my 36T 350s are perfect. I love the sound, ease of maintenance, bullet proof reliability and the 10* of engagement is just fine. I have the newest versions of the 350 with the classic ratchet and not the EXP version, and if DT ever changes all of their hubs to the EXP style, then I'll go back to hope hubs. I don't like riding with someone with I9s, much less having that sound on my own bike.... just not my thing. I have been looking into an Onyx hub as total silence would be amazing, but their reliability issues and price has so far kept me on 350s.

Simply put, I love high engagement hubs. Since moving to the hydra, high POE is critical when pushing through technical sections. If the loud buzzing is too much, I would suggest an Onyx hub as they are silent and have instant engagement. I’m used to the pedal kickback and have grown to not worry so much about my suspension being hindered, rather enjoying myself out on the trail with a loud, high engagement hub is what I love!

[@taylorstarcevic1015]

Hail Hydra?

[@devincrighton4376]

Agree, I have ridden both I9s and Onyx hubs and they are both amazing. After riding them for many years if I rent a bike with a DT240, the lack of engagement points is extremely noticeable on techincal climbs or climbs with lots of rocks to catch a pedal on where you may have to back pedal to retime your stroke. This is super common where i live and ride, Arizona, Utah, Nevada. I think if you ride somewhere this isn't an issues you could probably be comfortable with the DT240s.

Pedaling between features and getting up tricky climbs is much more immediate

[@jeffroper5943]

The stans neo hub is such garbage. I broke 6 of them in one year. The pawls and bearings would get crushed and destroyed almost immediately. One of the worst mtb products i've had to deal with.

[@Bonanno13]

I have an Onyx on my single speed full SUS bike and a 5-degree Stan's hub on my XC. The zero is much better in technical, slow speed work like riding a single speed uphill. I like the 5 degree for faster riding mostly because of free play in the hub. It really does soak up some of the feedback to your feet. I feel that it is important when standing on the pedals for a long time. Also, the Onyx is dead silent, I surprise hikers and runners quite often, especially when they have headphones in. The noise of hubs is helpful on multi use trails.

[@sluette]

The engagement angle of the I9 is very impressive, but you should also keep in mind that this is only achieved because only one of the six pawls is engaged. With spur gearing, the entire wheel is engaged, which makes a much gentler power transmission possible.

[@se4g4e]

Not quite true. Hydra hubs engage multiple pawls as torque is applied. It's not just riding on one pawl.

I do primarily enduro mtb. All i can say is once i went with a fast engagement hub, there is no going back. If there is any pedal kickback, i never felt it.

The trails i ride makes one really earn the gnarly descents. Each to their own needs and requirements me guess🙃

[@RiddleKingOnline]

I'm glad you touched on this. Rear suspension only works as designed when pedal kickback (i.e rider weight against the kickback) and braking are not inhibiting it. As a dual suspension guy, less points of engagement is absolutely key to getting better suspension, as is knowing when to get off the brakes and let your suspension do its job. I recommend everyone tries a) taking the chain off for a run and experience zero kickback, and b) jump up and down on your bike with the brakes on then again with them off to see how much it jams up your travel.

[@paradox963]

A high POE hub will definitely show the weak spots in a suspension design, pedal kickback can be almost eliminated with proper suspension design.

[@laurynasjagelo5075]

Something to point out; The wheel doesn't provide as much pedal kickback when the wheel is turning. Rather it is under braking and in big (climbing) cogs at slow speeds is where the effect is noticeable the most. In mid-small sprockets and at high (wheel rotational) speeds the pedal kickback in negligible

I think in my opinion as high engagement as you can get is a must when traction can be an issue. If its muddy or if youre like me who also commutes in the winter regardless of there being snow or ice on the ground. I would struggle without high POE because when your rear slips at some point that momentum transfer and the brief moment of acceleration on the pedal can cause your rear to slip even more. I've wiped out before and had near slips in icy or really slick situations. If you arent dealing with that sort of terrain high POE is a Nice to have. Not a NEED to have.

Changed my DT swiss ratchet from 36 to a 54 with 150mm rear travel and i only have positive things to say.. for me it actually feels like it gives less kickback, sure i know this isn't true but the fact that there is less give in the system, means that the kick back is less jarring and is more predictable(the reset after the kickback). So far the upgrade has been solid and money well spent and i have advised all my friends to do the same upgrade since it is one of the best things i have changed on my bike... and this is from someone who didn't expect to feel any big changes from the upgrade

[@paradox963]

Living where I do there are a lot of flat trails but a lot of them are tight and twisty. And this is where I notice the slop in low POE hubs, when you are constantly having to get on and off the power and may only have time for one or two pedal strokes before the next corner. I think like many things in mountain biking ignorance is bliss, you don't know what you're missing till you try it, then you can't go back.

Fabulous technical video with great visuals. Would be cool if you can spin both hubs so we can see if all those engagements result in a higher drag coefficient resulting in fewer wheel revolutions. I would add if pedal kickback is an issue it can be completely eliminated simply with an 'O-Chain' 👌🏻

[@johnnyweekend]

@@LoveMTB Thanks for your reply! I agree 100%. I cannot confirm the long term reliability on the O-Chain, nor do I feel that huge of a difference when it comes to pedal kickback. And I do believe bikes that have a high pivot/pulley might be reducing pedal kickback by 10% but end up creating a list of new reliability issues, not to mention the extra pound of using a longer chain. IMO, pedal kickback can help riders with an average cadence. For the drag comparison, I would also agree that it'd be quite difficult to be accurate.

[@lazylearner967]

Other than OEM hubs, I have only owned Hadley and Chris King. Kings are really nice and is the only reason I don't sell an old bike with the old 135 rear dropout. Another thing to discuss that is hard to quantify is drag. The Kings seem to have such little drag. I only notice this when cleaning the chain and back pedaling it on the work stand. Kings never need service once you are past the first 1k miles. They just keep going and stay clean. My old king hub has over 15k on it and although I have had the shop open it up 4 times, the grease is clean and bearings feel perfect. Personally I am not a fan of loud hubs. My Kings are far more quiet than most OEM and well as other hubs. I think Onyx is the fastest engagement and is also silent. But I can't get over the weight of that hub.

As soon as a bike starts rolling pedal kick back isn't an issue with any modern suspension design. I've gone from Stan's Neo hubs (L), to I9 Torch (H), to Hope Pro 4 (L), and now back to I9 Hydras (H). Most of the climbing I do is relatively technical so swapping from high to low poe is extremely noticable in that regard, hence being back on hydras. DT Swiss's logic really only applies to a static bike and is just a way for them to market their ratchet design. There's no right or wrong answer, but for me after spending time with both, low poe just feels clunky and harsh pedaling up technical climbs or through undulating terrain comparatively to high poe.

[@daniell4711]

In my early days of MTBing, I had moments where the low POE infuriated me when trying to get the bike going on a tricky and precarious part of a trail, so I say higher POE is better. 690 pt is cool, but I’m more than happy with the 108T upgrade on my Bontrager RapidDrives and would still argue that is the cheapest way to get a high engaging hub without forking out for i9s

Another great video as always. Thou these are amazing hubs to say the least. I do think they are more than I need at my skill level. Just got my set of Bontrager Comp 30 and they will be perfect my my new build and rides. Thanks again 🍻

when i got the new ratchet exp 240s i wanted quality, weight savings, serviceability and customer service for any future issues and well, a 240 is forever points of engagement t is a very very tricky thing since its also related to the gear ratio and length of the crank too so ya, too subjective to pay for durability and reliabilty is forever

[@jamest2660]

High engaging hubs definitely help with tech climbs, especially in areas were crank/pedal strikes are common. I also think that the I9 1/1 hubs are high enough engagement for this. I don't think the Hydra's super high POE is necessary.

[@Clint_the_Audio-Photo_Guy]

Maybe if you're a Trials rider, you may find some benefit in the ultra low POE hubs, otherwise I think I'd prefer the 36 POE hubs. The sound alone on the Hydra is obnoxious, IMO. It's already hard to talk to friends while riding with a loud hub. The Hydra probably scares the wildlife away in the woods, lol.

[@LoveMTB]

I'm with you, perfectly fine on 36T

[@ANTheWhizkid]

I ride trail/enduro - Hands down, no upgrade changed my riding as significantly as the hub and bb -Dt makes awesome quality products and the 54 star ratchet is surely something I would pick as well, but when the box with the writing "Handmade in Asheville" arrives and you be holding the product in your hands, you know why you wanted the hydra instead and suddenly forgot the money that you´ve spent. However, I notice that with every track stand, every climb and tech trail, that it was worth it. The product just makes fun and has a nice sound too.

[@Bittersfamily0424]

My bike came with DT Swiss 3 Pawl 370 hubs. I actually wore that hub out. DT Swiss laced up a 350 hub under warranty. I put 54 POE ratchets in the new hub. I really liked the quicker engagement for all types of riding I do. After that I wanted the i9 hydra wheel set. Had them on order for over six month and never got them. So I canceled my order and purchased a new Rockshox Zeb Ultimate. I will say that I am still very pleased with my DT Swiss wheel set. I feel like the new fork was a better upgrade over all.

[@Bittersfamily0424]

@@LoveMTB It is a lot more plush and allows me to hold a line easier in rough sections over my Lyrik RCT3. Overall much more confidence inspiring.

[@onilovni1234]

3:47 newer 12 speed drivetrains and smaller gear ratios rendered the 54t ratchet less enjoyable because the crank spins less than the back wheel in the 3-4 first cogs. All this backlash means you feel a strong kick in the pedals every time you accelerate and this is pretty annoying especially on a XC Hardtail. I'll try the I9 Hydra hoping this solves it.

[@alexisrodriguez6526]

Y'know, I never paid attention to POE until now, and I may have yo get a higher engagement hub due to my love for turning every road into a technical climb, where I live the streets are always broken, and the sidewalks look like a freaking motocross trail due to broken concrete and getting lifted by tree roots, so maybe in the future I'll invest on a hidra hub for my bike, but not at the moment

[@BH-cy9tb]

Very interesting. I have industry 9 hydra hubs on my ebike and over stock there is a measurable difference BUT I just got done building up a 2019 stumpjumper alloy and bought a new rear wheel that had 54 Poe and honestly no real big difference between it and the hydra at 690 Poe.I even upgraded the new rear wheel to 108 Poe and between the 54 and108 no discernible difference. I think once you get to around 50 Poe there are diminishing returns. Almost everything we buy into is because of marketing hype.

[@sebastianjost]

Also note that the engagement angle at the crank depends on the gear you're in. So if you are in a very low gear like 32-50, you get less than 10° with 36 POE.

[@sebastianjost]

@@LoveMTB you still had the formula in the video at 2:45, so that's perfectly fine. 🙃

[@polishguywithhardtospellna8227]

Fully agree, yet i keep forgetting that gear ratio stuff and just found out for sure(?) that pedal kick back is not really possible at even mild speeds. But still can't see much point to upgrade from 54 to 108. Would not like additional noise for sure.

[@BH-cy9tb]

@@polishguywithhardtospellna8227 between 54 and 108 not much difference in sound.

[@meliodashadeyoshi2115]

Even if there very similar it's like going from a four cylinder Honda civic to a Lamborghini in the sound differents when upgrading to the hydra hubs.

[@mcsweeneys3383]

36PoE is just right in my opinion.

[@wills4343]

I upgraded my DT 3 pawl wheels to I9 Hydra last year and it's been worth every penny. I have previously owned King and Hadley hubs. I would never use anything less than 72 Poe. Especially when climbing it makes a difference.

[@ХристоРъцев]

I like the idea of a high POE hub for my hardtail (no rear suspension, no problem with pedal kickback) but I just hate loud hubs! I like silence when riding on the trails, not listening to this terrible noise. I would love to get the box stealth rear hub, but it is really expensive :(

[@antonioruiz6723]

Great video! I think for myself or most non professional riders you don't need to spend 3 times the money for that .5 of engagement. But this is a consumerism industry so... Whatever keeps the big brands to improve their products, eventually it will benefit all of us.

[@serhiirudenko6183]

I'd like to have a silent hub on my gravel bike. Also those hubs have almost instant engagement, that should be really good for uphills. They're hard to find and pretty expensive but someday I'll get one.

[@LoveMTB]

They do exist but the price is🚀🚀🚀

[@Rhums]

Personnaly, I hate freewheel noise, that Hydra sounds like a nightmare. I already didn't like the DT Ratchets for that very reason. I have some more traditionnal Aivee freewheel on my FS Cross-country bike, Once properly greased, it's silent ! It's a pure joy when coasting and I have zero issues with engagement even on technical climbing.

[@zdravo4]

Agree, if I got it for free I wouldn’t like to use it

[@believe8263]

You should try Onyx hubs. Instant engagement and zero sound. It's so nice being able to hear your bike instead of your hub. I can actually hear my tires when they begin to slide and lose traction.

[@zdravo4]

@@daispatrick exactly. I remeber when I got my first car, I wanted it to be loud, very loud. So I took it to the exhaust service to remove middle silencer completely. The sevice owner told me, “tomorrow you will be begging me to put it back” and so it was. The car was so annoying loud that I drove it slowly. And yes, in few days I went to exhaust service to put the silencer back

[@RyanAmirault]

For everyone commenting and use Industry Nine Hydra or 1/1 - have you been able to notice a difference between those two hubs of 90 vs 690 POE? I'm personally down to the DT 350 (with 54t upgrade), Hydra and 1/1. I'm leaning towards a 1/1.

[@jimm244]

I’ve been riding 1/1’s for two years; 4°. I just got a sick deal on Hydras. Yes, one will notice the difference. Thhe Hydras are awesome, but IMO the 4° engagement on the 1/1’s is enough. I’ve never ridden a DT star-ratchet (only their 3-prawls), but I probably wouldn’t notice much on-trail difference between 6.6° and 4°. Personally, I’d be happy with any of those options. But if the 54 tooth isn’t “enough” (and not accounting for price, build, rims, etc) I’d skip over the 1/1’s and go Hydra (but again, I think any of the options you mention would be solid!).

[@shwndh]

High POE just sounds and feels high quality. I’m completely happy with Hope 44 POE.

[@wiljaq2773]

Dude - it depends on what kind of riding do you do. I had a DT Swiss hub and upgraded to I9 Hydra with 315 Carbon hoops and it was a fantastic improvement for my bike. BUT, I ride in an area with a lot of technical climbs where I need instant engagement of power. If I were mostly going downhill or easy rolling trails my old DT Swiss hub would have been fine. BTW - I had I9 add more grease to my Hydra so now it doesn’t make that loud noise.

[@Ropetable]

It would be cool to have a hybrid hub, having high poe in the up and down position, and low poe in the position where both cranks are level. This would eliminate crank kickback when descending (cranks level) and have high poe where it matters, the up and down position when you need max leverage. Also the sound would be sick XD

[@jbw5485]

How does pedal kick back work when the rear wheel is actually rolling down the trail?? Seems like the higher the POE the more kickback at slower speeds. Less play in the driveline. 🤷🏼‍♂️🤷🏼‍♂️ but if the rear wheel is rolling forward……..wouldn’t pedal kickback be negligible?

[@thecount1001]

i find the 10° engagement fine, no big problems, but i hella love my Hydras. a beautiful feeling and sounding hub, especially with some Dumonde tech hub grease applied every couple months.

[@brassmnky33]

Important to remember that when climbing you’re in a lower gear so ten degrees might end up being more like 12-18deg at the pedals and when in a high gear downhill it’s much less.

[@brassmnky33]

@@LoveMTB I think you can calculate the POE at the pedals. For instance a 30t*50t would end up being 16.7deg and a 30*10t would end up being 3.3deg at the pedals.

[@brassmnky33]

Putting i9 on your single speed is kind of a waste of money for this reason unless you’re racing BMX or something.

[@jpensirikul]

Hey great stuff! Love the detailed product reviews. Looks like you've got Berd spokes. There's very little 3rd party info out there. I'd be interested to hear your thoughts on them related to ride quality, cost and how much you think their impact can be enhanced (or nullified) by rim selection.

@@LoveMTB awesome I'll check it out

[@fattie2550]

I am running DT 240 Hubs with the 54T Ratchet. rides great

[@sebastianjost]

I definitely don't like too low POE. I think my old Gravelbike had about 16 points and my new (used) MTB has also below 30. Since I do somewhat technical climbs on both bikes and also occasionally try some Trials riding, that very high engagement angle can definitely be annoying and can contribute to not making it up a technical climb. I think anything above 36-70 POE should be fine, but there is also little disadvantage to more POE on hardtails. As a final question: do you know any affordable hubs with good POE (30-70) that are quieter than the dt swiss? I really don't like loud hubs. I feel like Shimano hubs could be an option for that but I'm not sure.

[@2wheels8est]

I'm looking allways for the sweet spot. I like loud hubs, quick engagement und an good reliability but also the price tag is important to me. I tried many hubs and my favorites are the dt swiss 350 and the Hope pro4 Evo! The Engagement is quick enough, with 36 top 54 engagement points, the price is good, they are reliable and also the availability of spare parts is great! Bontrager Hubs are also ok but Not in Terms of spare parts and longlivety. I think the Hub weight If not to heayy isn't that important because of the distance from the rotation center.

[@0815-j3s]

This hub has some conceptual issues: 1. you cannot remove the axle without removing the bearing=>bad. 2. The hub creaks. Maybe due to the axle, which is made of very soft aluminum. 3. The bearings are expensive but not very long lasting. 4. Almost no sealing. Instant engagement makes a lot of noise during downhill. I went back to DT Swiss 240, and the noise is much less. Maybe in combination with Ochain this hub works for DH.

[@LoveMTB]

Well some would argue that high engagement is even less necessary for DH!?

[@0815-j3s]

@@LoveMTBOf course; maybe.

[@jackfrost-fu7hz]

I had new wheels built with DT350 hubs, it came with the 18 tooth ratchet, it was horrible, the old XT hubs had better engagement. I had to spend another 100 dollars for the 54 tooth ratchet, so my economical hubs became expensive with the extra 100. I have a 2x11 setup and find the 54 tooth ratchet lacking in engagement.

[@michael_the_chef]

The 54t dt kit is great but not very durable, i am heavy and strong in my legs, was riding very agressively and in a rough, rooty section a few teeth of the ratchet got damaged because of pedal kickback. Also in cold weather it happens sometimes not to engage. Used a small amount of dt swiss supplies grease, so no user error.

[@LoveMTB]

And that’s why they don’t supply any of their wheels standard with 54t, even the new 240 comes with 36!

[@ksskchannel6978]

Very useful info. Thanks mate

[@mikekrasovec6390]

Most of my hub problems have been due to the freehub body seizing up, not properly locking up, bearing issues, not staying adjusted... I've got in my collection of wheels xt, xtr, 105, ultegra, dura-ace, king, Phil, dt 240 and if the hub does what it's supposed to do without giving me trouble, being easy to service and low drag I'm happy. I've ridden and wrenched too many hubs that didn't hold up, poor lateral stability, were a pain to work on,..

[@SubversionGarage]

Going from 10-degree engagement to 3.3 made a difference in some climbing situations, but can't really say I noticed much difference elsewhere. I would say anything 5 and under would suit most riders just fine

Does higher engagement hubs slow down the bike when free wheeling (when the wheels just roll and you aren't pedalling)? Compared to a lower engagement hub

[@virkelie2]

There are videos on KZbin showing how to increase the engagement of Bontrager hubs from 54 to 108 teeth of engagement (by doubling the number of pawls: 3 to 6). It seems an easy enough upgrade, but some say that increasing the engagement of a hub weakens the hub. Is this true? If it is, why would this be so?

[@LoveMTB]

It doesn’t weaken anything you just add another set of pawls 😉

we need to report points of engagement and angle of engagement... for some pawl based rachets, you can add more points of engagement without changing the angle of engagement
