An idiot mechanic’s Opinion on Shimano 12 Sp 105, Ultegra & Dura-Ace

A total opinion piece. Tell me i'm wrong as much as you like.
#Di2 #DuraAce #Ultegra

[@Sandzsteedt]

Here's a hot take from a professional bike mechanic of over 13 years and counting. Over the following years mechanical shifting will go away and then come back like Swiss watches as a premium item. Electronic shifting will become like cheap digital watches and be cheap because the same switches, batteries and motors can be used in all trim levels of shifting and only the external part materials and their weight will determine the level of quality of shifting parts. The only reason why the electronic stuff costs so much right now is that it is marketed as premium when in reality the biggest cost cutting will be in the electronic shifting. Electronics will be shared in all price points leading to overall lower cost to manufacture as opposed to having to produce loads of tiny parts for shift lever mechanisms to different tolerances out of different materials. So my prediction is that in the future the premium level bikes will have really nicely made mechanical stuff most likely marketed as authentic feel or some shit like that and electronics will be the bog standard in every price level. It will take time to get there but it sure looks like the future right now when you consider the speed that people are willing to buy the electronic junk in shifting and e-bikes etc. The trend seems to be that adding a battery and electronic function is somehow sought after at the moment and mainstream consumers are lapping it up no questions asked. Of course there will always be some Far-East factory making parts for whatever is the most common old mechanical item on the market at the most lowest price possible out of garbage materials. But when it comes to new western world quality level consumer bikes the trend will be as I described above. The biggest joke this far that I have seen is this in the same bike: (Number is the amount of batteries) E-bike battery (1) Sram Flight attendant shock + fork + crank spindle sensor (3) Sram AXS Shifting 1-by (2) Sram AXS dropper post (2) Add into that the common stuff like: Bike computer (1) Battery operated front + rear light (2) Complete bike ready to ride with accessories has 11 batteries to keep track of by charging or swapping as needed. Must be fun preparing for a ride with that bike. I do not like where the bike industry is heading and will keep riding my mechanical drivetrains as long as I can, but it will get increasingly more difficult as time passes and planned incompatibility and dwindling spare parts supply creep forward.

[@wjlasloThe2nd]

This a million times over. You'd have to really reduce the functionality of an "analog" non-electronic bike to get me to say that on balance the decked out electronic bike wins. I love being able to get on my bike whenever I want and go wherever my muscles can take me, no gas, no charging, no batteries that wear out even when sitting idle or die in cold temperatures

[@markhall6026]

Great Post this is like manual gearbox in a porsche it's in the GT3 with is porsches premium car

[@out_spocken]

Though I agree with you in what will happen. I disagree that electronic is bad. I've been using di2 for almost 10 years now and it is genuinely the better choice for me. It stays in tune and doesn't require any cable adjustment or replacement. There's no need to double tap the FD at least on Shimano to better align it depending on where the RD is. Sure...it's bloody expensive if you knock or wreck a piece of di2 gear..but if we remove price...di2 offers a better experience. Using something just because we have used it is a stupid argument. Equally just as suggesting all progress is great. But how is electronic bad?

[@icenijohn2]

I was a mechanic and service manager in Southern California bike shops for fifteen years, starting when Super Record was still available and when 7400 Dura-Ace was competing with Superbe Pro, and getting out of the business when electronics/hydraulics/planned obsolescence/limited options/etc etc (i.e. all the trappings of a modern consumer society) became the new normal. For me, a bicycle should reflect minimalism, simplicity, repairability, versatility, elegance, in other words everything that bikes these days are not. I am an unabashed retrogrouch, and all the happier for it! I'm so glad that my bikes are essentially 100% reliable and need no batteries for them to function. My touring bike, a custom 531ST with an eclectic mix of simple proven parts, has taken me across India and Nepal with no, and I mean absolutely zero, failures, not even any flat tyres; if I'm in the middle of New Mexico or crossing the Mojave Desert hundreds of miles from the nearest decent bike shop I cannot risk any breakdown at all. Would I have achieved this level of absolute reliability with electronica? Obviously not. Yes, traditional bikes like my six beauties are laughably anachronistic these days, and they're all the better for it. I'm so glad I got out of the bike world's ever-increasing cynicism and disdain for their customers when I did. I look at the current marketing-led lunacy from afar with pity and sorrow, and I try to relate to all those naive suckers who have been mindlessly duped into it, but to no avail.

This has quickly become one of my favorite channels. Well reasoned opinions, rational and balanced (things like value for money taken into account, serviceability and fit for purpose depending on type or style of riding). Majority of the 'objective opinions' expressed by YT channels are actually largely unsubstantiated preferences (often by dyed in wool roadies or touring cyclists prone who blindly favor tradition over progression) or equally groanworthy , totally biased 'objective sponsored content'. Having preferences is fine, but shoving it down our throats as an absolute truth is grating. Kudos to you and others of your ilk (Peak Torque, Hambini etc).

Most of his takes are so inconsistent with previous ones he’s unleashed. He's just as dismissive about "professional" cycling culture as he claims "professional" cycling culture to be. Everything is for clicks and views and likes and traffic, including being an exaggerating, excessively opinionated retro grouch. The guy literally spends hours talking about old tech/being less wasteful/bringing cycling 'for the people', then proceeds to say everyone NEEDS a $500 boutique square taper crank, $300 artisan cable disc brake calipers and a "humble" steel frame that costs more than many mid-range carbon framesets.

Seems like an odd limitation, since they accept firmware updates and there's no real reason except it puts more money in their pocket.

[@w.1929]

Still very happy with my Ultegra 11 spd mechanical set. Every shift is bang on. Why bin the 105 mechanical option, Shimano? Past Ultegra would have made a superb new 105 and not force customers to a much more expensive purchase of an electronic groupset no one needs.

[@iMadrid11]

Electronic groupsets is great for forced obsolescence. As you can't buy new 1st gen. Di2 parts anymore. Mechanical groupsets can last an entire lifetime of a bike. Which means there is no end of life support for electronic parts by the manufacturer after 5-10 years.

@@YuudachiPois yeah I see where you are coming from and I totally do understand. Still, to force this upon people looking for a mid tier groupset on somewhat of a budget just isn't right to me. They should have left a choice between a 105 electronic and mechanical being the trickled down Ultegra, my opinion. It will serve the Sensahs and whatever Chinese brands out there to take a larger share of the market, well that's just the way it works.

You've just answered your own question mate. When in doubt, follow the money.

[@monetaryjack1705]

100% agree on the gearing issues on bikes, and often wondered why they don't offer the 46/30 (x 12/13-36?) in 105- lets face it most bikes are massively over geared and they don't seem to consider that some of us live in places like the Scottish Highlands where descending at 70km/h is FAR less important than getting up a long steep hill, many of us are not that young, or are not the "perfect weight"... I've an old Carrera TDF that has only the original frame left on it now( Triggers Brush springs to mind...) which came with 2x7 Tourney and a lowest of 34/28 on a 12.5kg bike, that's now got (ebay) Tiagra 4600 on it so I could run a M-592 MTB mech on it and it has a low of 34/36 but I'm planning an 11-40 cassette as it will handle it easily.... and when the chainrings go eventually I'll probably put on FSA Tempo 46/30...It's my winter bike now, My better bike for summer has Sora R3000 ironically with the same derailleur, and I've split 2 and built a USABLE cassette 14-36...... (but got a 105 groupset from CRC for £299 for "future proofing", keep it in storage for now lol)

[@Mapdec]

Hey. Good skills on all that compatibility.

[@lastfm4477]

Why do you need 105 in 46-30T when you can get that in GRX? You can mix and match GRX and 105/Ultegra. I make 12-36T 10-speed cassettes by taking a 11-36T and changing the 11T for a 12T (since the 2nd smallest is a 13T). Brilliant "gravel"/CX cassette with a 48-31T or 46-33T crank.

[@onthemoveot]

I absolutely agree. I’m trying to put compact on a lightly used Evo Hi mod that I just picked up for second hand recently. It’s taken hours to try and find a compact and have had to go down to ultegra for the front rings and rear cassette and need to swap out the RD to accommodate the 32T cassette I want. Even then on some climbs I can’t maintain the seated cadence I prefer. I get I can use GRX but that’s not the point. Shimano should be prioritising the consumer and the majority of us don’t needs ‘sub compact’ in a road gruppo

[@monetaryjack1705]

@@lastfm4477 I thought the chainline on GRX was wider than road because it's ""gravel"? Maybe wrong....

[@monetaryjack1705]

@@onthemoveot Ok, bit confused at your last sentence? Are you pro or anti "road spec" 46/30?!! .... the vast majority of us don't need 36/52 or 39/53 and that's always catered for, so why not offer 46/30 sub-compact in road spec(not gravel) for those of us who care for our knees lol....bet they'd be surprised at how many they shifted and for a lot of folk the 11-13 cogs might finally get some use....Doesn't affect the frame manufacturers and chainstay position, maybe make that braze on FD a bit longer and lower down? Doesn't mean bigger and heavier cassettes to get lower gears when you've shrunk the chainset significantly. It's funny but when Black Friday is on and groupsets are on offer it's always the silly high geared cranksets that are left over on offer with 175mm cranks....mere mortals don't want them clearly....

I'll stick to 9-speed mechanical, easy to maintain, mix and matchable, reliable and affordable.

[@whssy]

I agree. Still on 9-speed Record from 98 on one of my bikes. Bike gear has gone downhill since then. If it wasn't for the stupid HT BB, 7700 DA was peak Shimano. Until your rear mech fails and then you (and I) are stuck with what's available on the second-hand/NOS market.

[@worldofameiso5491]

I think I'll stick with 10 speed mechanical Dura Ace and Record thanks - too many electronic gimmicks in the world, I don't need more on my bikes.

[@cjohnson3836]

Yeah. Given the amount of gear overlap, I don't see any real reason to go above 10sp on road unless you are daily riding up the Andes. I also have to work on my own bikes so electronic is simply a non-starter for me. I can reasonably confidently tear down a mech shifter.

After watching this very insightful view into the new electronic groupsets and disc brakes im so pleased i bought a couple of R7000 105 rim brake groupsets when they were £300 on Wiggle...thats me sorted until Tiagra comes out as 11 speed for replacement parts.

[@GNX157]

I’ve mentioned this many times before here and elsewhere. A class action right to repair lawsuit needs to be brought against Shimano and the others, due to the extreme cost of these electronic parts. Mandate that they sell every part of a derailleur etc as well as tools to do the job. Also Shimano should be mandated to provide a regional repair center where these parts can be sent for repair, or exchanged for a refurbed model when damaged beyond repair.

Yes. Refurbished parts would be so cool.

I would generally agree to you, but.....takes too long or/and to do this process takes too long.

The solution might be some chinese company that attacks this foolish overpriced market really hard. If I would be a chinese/indian/arab billionaire with too much money....i would buy Campa and would attack Shimano/SRam as hard as possible, they really deserved it.

[@rosomak8244]

[@martindoonan198]

I think you've hit it all spot-on. Too many of current developments are moving towards less compatibility and more future obsolesence. Even simple things like 3rd party cranks & chainrings, let alone the difficulties of all the electronics. Once upon a time, Shimano were the epitome of cross-compatibility between groupsets and raod/MTB kit. And what ordinary cyclist needs an 11t or 10t small cog? I've run 50 or 48 x 12 on road bikes for years, and theat hasn't slowed me down on even big alpine descents (and I've only ever come across 1 amateur rider faster than me downhill). Personally, I'm a dedicated Campag fan for road bikes. I've found it bullet-proof reliable, easy to set up and needs no adjustment after intial bedding in. Never got on with the ergonomics & haptics of Shimano. I have just fitted Rival ETAP/Easgle mullet to my new gravel bike, though. I'm blown away with how easy to set up that is and like you say, has the easy interface through the app (which isn't even needed for basic set-up). With the wireless, I can set up the bike easily for both drop & flat bars making the bike even more versatile. The Rival shifters also have a great shape for using on flared bars. If only they'd ditch that stupid flat-top chain and the different cassette standards (XD/XDR) to make the system even more cross-compatibile.

[@Mapdec]

Thanks for the input. Great points.

[@Membrillo81]

I agree with you about gear ratios. I'm using 46/30 and 14/40 with 105 R7000 (front mech is Ultegra). I live in Taipei (lots of mountains) and constantly hit 10%+, 15%+ and more often than not 20%+. The original 50/34 and 11/34 wasn't nearly as low as I needed to explore the many small roads around here. Judging by the number of cyclists I met in the main roads (usually with more reasonable gradients) and the number of cyclists I met in the secondary and tertiary roads (usually with crazy gradients), more people would benefit from lower gears to be able to explore the quieter roads. My knees and my heart loved the change. My chain too, because I can have a better chainline for more time. I don't care at all about pedalling at 60km/h. Not wanting to win any race here.

[@draugmithrin]

Looking after my knees and having the choice to ride in a lower zone or high cadence when climbing is essential to me. Use 50-39-26T chainsets on most my bikes.

[@Membrillo81]

@@draugmithrin I like the simplicity of 2x more than 3x, although it needs a wider cassette for similar range. Also, in my case it would required a shifter change. But 3x is definitely an option.

Funny you mention “once set up properly”. My SRAM etap front derailleur kept dropping my chain not matter how much I tweaked it.

Like this video format 👍 Repair prices quickly get expensive with these new Shimano groupsets. A customer of mine recently broke a 12sp ultegra rear mech and it cost just shy of £400 to get the bike back on the road. That did include a new hanger and some work on the rear wheel (spokes, truing, retentioning) but the significant cost was in the rear mech. Agree fully on the charge cable, should be USB C and the diagnostic box, stupid and impossible to purchase. Just build it into the PC or phone software.

I've been a Shimano guy for years, but with the latest Shimano 105 Di2 I'm completely disappointed. Only two cassette options 11-34 and 11-36 and rear derailleur with min. low sprocket 34T. That means you can't even use an 11-30 cassette from Ultegra 8100 or Dura Ace Di2 9200. Totally limited selection. Big minus for Shimano.

[@davidvannewkirk6426]

I've ridden all the major electronic groups, and settled on Shimano more for ergonomics and brake feel than shifting function. All of the major groups seem to move the chain well enough. The GRX Di2 levers are simply the most solid-feeling lever made, which makes them perfect for rough surfaces and cyclocross. I moved to the new 12-speed Ultegra on my road bike, and love the inward cant they give to my wrists. As for your comment on wiring up the levers on the new 12-speed Shimano - no. Wireless is the way to go. As a mechanic, I absolutely loathe the drive toward more integration(hiding cables), but given that is the direction the industry seems to be going, having fewer cables to force through a headset is a good thing. Sure, the battery may be a little harder to track down than a 2032, but I'll take that over feeding one more wire into a Tarmac.(FWIW, none of my bikes hides a cable in stem, headset, or handlebar)

[@LainOTN]

As a home mechanic and user I went to wired, 1 charger for all and 50% more range. it's no brainer as a user. I install once, but charge/change cells more often. I hate AXS because of that (I have both) wireless is not the way to go at least for 2x.

I’m fortunate to own both the R8000 mechanical and the new Di2 12 speed. While I like the Di2 there are many items I don’t care for, many you listed. When people ask what is the best way to go, I recommend 105 mechanical. All you need and nothing you don’t. Buy better wheels and tires instead.

[@cjohnson3836]

The best thing about 12 speed groupsets is that it means the suckers are unloading their perfectly awesome 11spd components. I don't think anyone not actually on the books of a race team is getting any quantifiable benefits of anything above Sora or Tiagra. Esp on road bikes. Roads are tame, no one needs all this bloated mess on their bikes. And more, none of us really benefit. "But my gear steps!!" Gear overlap says hi. But hey, I just snagged a pair of GRX 2x11 shifters, basically as new condition, for $200 and a pair of 105 calipers with about a month of use for $80. So everyone keep doing what you're doing. Meanwhile, I'm just going to flip the left shifter for $150 and find a decent used 810-LA and probably only be in the hole for about $100 once the dust settles.

Main reason I don’t like SRAM is because they use DOT brake fluid. There’s just no need for it, and it’s a nasty caustic water absorbing fluid. There are minor things to hate but that one is unforgivable.

I would like to see more crankset options, in terms of crank length and chain ring size choices, spec'd on new bikes. If you look at Rotor's modular design, the crank arms are customizable in 5mm increments (great for a proper bike fit) and their one-piece double chain rings are a work of art. I run small cranks and therefore have dropped down to a 46/30 chain rings but Rotor make picking your choices a breeze.

Many valid points! I own the new Shimano DI2 Ultegra. I installed it myself this past August. It is a big improvement over the DI2 11 speed for the following reasons; much easier to install, no need to purchase a separate bluetooth "dongle" to communicate with the system via the E-Tube app, faster shifting on the front mech, much improved E-Tube app which aids in quick set up of both mechs and the wireless shifters work flawlessly. Here is the States we don't have a problem getting the 1632 batteries and I haven't needed to replace mine yet after 5 months of riding the bike a lot! Dislikes; cost, some chain noise on the cassette that I'v been unable to micro adjust away and I HATE the synchro shift which I promptly shut off. Other than that I love it and find it better overall than the previous generation. BTW I've ridden well over 100K miles in my career and never broken a rear mech. As usual I always enjoy your unfiltered opinions, its valuable work you're doing!!

I’m so happy to own an Émonda with mechanical Durace which weighs 6.4 kg. It’s 6 year old, I paid €3500 for it (brand new) and don’t see any interesting alternative right now. Outrageous prices, heavy and too much electronics.

[@auswi]

Love the analogy of Windows, Mac and Linux. This is my opinion on Shimano v SRAM. I've never owned SRAM, but when I look at pure spec's, they are heavier and more expensive. Two things that are important to me. I also use the hood top buttons to switch screens on my Garmin, which I believe SRAM doesn't have. Charging isn't an issue to me as I am used to plugging a proprietary cable into my bar end to charge it, and another set of cables for the Giant PowerPro. The main issue is that as the batteries last ages, you need to remember to charge them. SRAM has had the 12 speed for a while now, and personally, I am looking forward to my next bike with an 11-34T cassette. My previous bikes were 11-25 10-speed (then upgraded to 11-28), 11-30 11-speed, and next will be 11-34 12 speed. Essentially the gearing will stay the same, except I get an extra cog with 34 to deal with all those hills that just seem to get steeper as I get older. The last 10 years has been Ultegra Di2, and with the latest upgrades, I understand that the only significant difference between Ultegra and Dura-Ace are the materials used and subsequent weight. I am not planning on any racing, so Ultegra it is. I'm not a mechanic, but in 10 years I have had zero problems with my Di2 group sets. I am sure that SRAM is fine, but in my case, there aren't any value propositions that would make me want to switch from Windows to Mac 😉

[@indiebikes]

Been riding 105 Di2 thru winter 50/34-11/34 on a Diverge with 32c tyres. Have to say it has been excellent so far. Brakes can get a bit noisy if not cleaned after 2-3 rides, only takes a blast of brake cleaner and a wipe. Front shifting is the real winner for me which is so much better than all my mechanical groups and I have them all. Ultimately it’s all about choice and how lucky we all are to have so much of it. Riding R7000 one day, R8000 another and R9100 on a steel framed custom build Sunday ride, no better time to be alive.

[@andrewc948]

I would suggest that electronic shifting is accurate, and happily, for the manufacturer, cheaper to produce. Business is always reliant on profit and the accountants trump engineers. The SRAM adoption for me is complicated by the affinity of brake fluid for water. Mineral oil is less aggressive on paint and more suited to the cyclist's moist outdoor environment. My head says Shimano Ultegra , 105 or GRX mechanical are probably the pinnacle of shifting bang for buck. Add to that my GRX has just gone 6000KM on one rear shifter cable. I think that's pretty good. Forget the battery.

I don't have a problem with 12 speed. I don't want electronic. I have AXS on both of my MTBs. On my XC race bike, which I rarely ride, it's fine. Except I almost learned the hard way that the shifter battery doesn't last as long as I thought. But on my trail bike, I don't like it. I don't want to have to worry about a dead battery. I don't want to carry a spare on bigger rides (I killed one on a ride). I just want to be able to go ride it. And that's my issue with electronics. I commute daily, I don't want another battery to charge. Bad enough with my headlight, tail light, and Garmin, but technically I don't need any of those to ride (and I have charged while riding with a battery pack). I considered getting a dyno hub to make life easier, but I also love the feel of my race bike every day (SuperSix Evo is fully slammed). Oh well. Either a lower tier system, or Sram 😢

[@paddyotoole2058]

@@nellyx1x493 Hi - tbh although the chain peening is the official Campagnolo recommendation, I’ve never bothered with it. I just use a regular chain splitter and then a YBN quick link to join the chain and never had any problems. I prefer to do it this way as I use a waxed drivetrain and I remove my chain to clean and renew the wax in a crock pot every 300km so using a quick link is best solution. As regards special bb tools, more major / less frequent work on bike like this I leave to my local bike shop mechanic anyways. Pulling / changing / checking the BB is a once every 18 months job and I leave that to the professionals like the bloke in this video. So in short, no special tools are required subject to the above and depending on how much you want to do yourself.

At least with 11 speed, you could still get an 11-25 cassette. My 7800 10 speed group keeps holding on. You can't even buy a good quality Shimano rim brake group anymore.

Whenever direct comparison is involved it's always going to divide opinions, that's natural. I do agree with most of it. I've been using Shimano since I can remember but the biggest disappointment came with Grx 2x11 where they wouldn't offer crank length below 170mm in 810 range. I somehow managed to solve my problem combining it with rotor but the alarm bells started ringing for me. I think they are beginning to lose their total domination; I think they are aware of it and I'm pretty sure there is not much they can do about it anymore (look 5-6 years back how many bikes came of the factory with SRAM vs how many You see nowadays). Would I choose Sram over Shimano? Maybe but I think AXS is a platform with much greater and faster improvement potential than Shimano even with current 12speed so I'm expecting things like automatic shifting based on cadence to be much likely to happen in AXS platform than Shimano. One thing that I totally disagree though is raising the argument of the system brain being stored in the rear derailleur and prone to expensive repair/replacement in the cause of crash. Yes it's true but it's true for BOTH Shimano and SRAM and for some strange reason it's being identified as a biggest CON against Shimano and not even part of the conversations in case of SRAM - strange... to me at least. Interesting analogy with the IT world and very correct as well. In the IT hardware world which is my daily playground the Good Better Best has been the strategy since day one but interestingly some time ago market has seen a switch to a two-step strategy rather than 3. We see the value for money customer and then we see the performance-oriented customer. The prosumer/enthusiast customers have slowly started to disappear to the point where it was no longer feasable to maintain. I honestly believe with 12 speed and electronic shifting it would be absolutely enough if they only kept 105 and dropped the pricing for Dura-ace slightly to please the rich customer. After all Dura-Ace is nothing but the cash cow for Shimano. Good material. Keep on with providing a great content. I'm a big fan.

Will it still be possible in decades to ride current aero racing bikes with digital gears, internal disc brake cables and a lot of proprietary parts?

Excellent point. Look at the vintage stuff people are still riding. All the "aero" stuff that Shimano introduced in the mid-80s is incompatible with anything and there are very very few people out there who are "into" it and spares availability even on the second-hand market is atrocious.

The argument that "it wins races"... has anyone seen how small the participant turnout is at amateur races? For road, 11 speed was pointless. 12 speed is pointless. Electronic is just a X2 multiplier of pointlessness in this context. Electronic shifting is great for beginners though as it enables automatic front mech shifting without cross chaining. Take away the front mech and it is entirely irrelevant. Everything since 7800 series DA (HT2 and cassettes with an 18T on almost everything - but I preferred "clothes line" 7700 cabling for accuracy) and 770 series XT (the first time Shimano nailed front shifting and disc brakes on MTBs) has been a lateral progression where upgrades have been introduced to "fix" problems caused by a previous "upgrade". And don't even get me started on how even beginners "need" carbon rims these days.

Good point re 1x12sp. I started roadccling just at end of 9sp. 2x 11sp is sweet spot for me ,as good for my 34x32 smallest gear for the steep stuff.

Great video. Charging port near to the ground, hard to reach, but at least gets all the grime from the road. How long will that flimsy cover hold up? Add in a non-standard plug and a battery that's hard to find in shops... Seems like it was designed to be a pain in the butt and a money pit. Don't buy until they sort out their quality-of-life design flaws maybe in a next iteration.
