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

[@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

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).

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.

[@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

@@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....

[@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.

[@YuudachiPois]

[@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.

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.

[@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.

Not to mention that some gravel bikes also have 1:1 or slightly lower as the lowest gear.

[@joelv4495]

Absolutely agree. I’m putting together a “gravel race” bike and still don’t feel the out of box gearing on GRX is low enough. I chose the 810 48-31 chainring and I’m hoping to pair it with an 11-40 cassette on the GRX rear mech, which isn’t officially supported.

[@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.

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.

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

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.

I didn’t necessarily think I needed 12sp but I do actually like the extra gear. 50/34 with 11-34 is ideal for me and where I ride, same as what have on my 105 roadie but with the extra gear. Love having the climbing satellite switches.

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.

I've never run out of gears (nor for that matter on my mountain bikes over the years)... (Except on my 3 speed Brompton, but that's a whole other problem 😂). However, I do covet lovely, shiny, expensive stuff tho, so maybe when I win the lottery I'll be able to get something with electronic Dura-Ace on it. I can dream... I would certainly like to try it out, see what the real difference is. Good luck in your hunt for diagnostic boxes and 1632 batteries 😂👍

[@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 😉

[@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 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.

Is digital gear shifting the end of vintage racing bikes? Until a few years ago, I always took part in the OPEL cycling tour in Ruesselsheim in southern Hesse (Germany). There was also a vintage tour with OPEL bikes, production of which stopped in 1936. 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?

[@whssy]

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. This is the future I predict for electronic shifting until a "standard to be followed" is determined.

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!!

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.

For Road I’m exclusively Campagnolo and have been for over 20 years, but there is a real lack of any info out there doing in depth direct comparison of Centaur v. Chorus v. Record v. Super Record other than price and I think if you did that you would be plugging a significant information gap.

Am thinking of switching to Campag for the first time ever next time around.

I could live with that... or is there more quirkiness to invest in?

[@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.

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.

[@simonwoodford8728]

Interested on your Tiagra comments. Most of my bikes are Campagnolo shod but both I and many of my riding colleagues found the 9x3 speed Tiagra groupsets a great introduction to road biking and the feedback I got from mechanics I trust was that the 10 speed Tiagra shifters were no where as durable. Have you had problems with the Tiagra 10 shifters or the Shimano Ultegra and Dura Ace bonded cranksets? As much as I have appreciated my limited experience with Di2, I love the experience of Campagnolo mechanical set ups better and see electronics and proprietary battery systems as an accelerated trip to bicycle obsolescence.

Yes. We have seen those issues. Very few.

[@whssy]

Taigra was always (IMHO) a downgrade compared to the RX100 it replaced (which on the parts that mattered was essentially 105 in a different colour). OTOH as a workhorse group, people would put it on winter and commute bikes and it wore out disproportionately faster than the groups people saved for special occasions. But it always "felt" a bit more toy-like than 105 up.

So basically it all boils down to the fact that electronic shifting is all hassle over hassle. Why is Shimano erasing the possibility of installing any type of groupset you like, just like Campagnolo does? I'm currently running a 1x system based on Campagnolo Chorus 12s and it's all brilliant!! Amazing and smooth shifting (mechanical, of course), and powerful braking (rim brakes). And it's way cheaper than Ultegra.

[@marcing7684]

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.

[@Mapdec]

Agree on the 2 tier point. MCW also mentioned in the vid that Ultegra 12sp is a bit underwhelming compared to the 105. I have the R8000, but now that SHIMANO have discontinued the 53/39 option for Ultegra I can’t see the point of it anymore. Why would you pay extra over 105 di2, especially when the weights are so similar…maybe Ultegra will be discontinued after this iteration?

[@JoshuaTootell]

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 😢

I'm hoping there's still gonna be 11spd parts for a long time, even if I have to tipex 105 on Tiagra or Claris parts!

[@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.

For as long as a mechanical rim braked Record group is actually cheaper than the mundane Ultegra, the decision for me is clear.

[@mtbboy1993]

I've not tried DI2, nor Sram AXS, but I use Archer D1X Trail, paddle remote. they have a left handed version too. The advantage of it is you can set it up to the speed I want, just make sure cassette and RD are compatible, you can use any mechanical RD. The app is easy to use, easy to set up and adjust each gear, change the setup. but you don't have to use the app to adjust each gear you can long press the button on the remote and and use the remote to adjust the position of each gear. So in my opinion this is far superior. Charging is easy, take off the remote connect it to a charger or you computer, for the shifter you undo the cap, and use a magnet to get the batteries out, but the new faster batteries increased shifting speed by 50%, but battery life is short, but they drop out of the shifter easier, so tilting bike forward helps, they come out. I have spare batteries with me in my backpack. I can adjust each gear, so when the RD gets sloppy and worn I can continue to use it longer. The remote is wireless. Ergonomics are great. there is also remotes for drop bars: MFR Drop Bar Remote which are universal, but also DBR Remote which integrates into the TRP road brakes/shifters.

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 vid, thanks, I personally always loved 105 10speed, still ride it now, but with less 105 parts, its light durable and well priced for top armature end, now its overpriced and out of reach, if you need that many gears you need to get out more as for being aimed at people getting into cycling, the biggest fear of new cyclists is coping with gears, and i still know loads of people who still do not use their gears to an advantage, they stick it in one and grind away at all speeds like they are driving a 5 speed car !! give them 11 or 12 speed they are overwhelmed, 3 £375 for rear mec !!!!!!!

Front mech shift anxiety is real!

I've been running a Rotor 46/30 crankset with Ultegra di2 11 speed 11-32 cassette for 2 years. Love it 👍 I charge it at the bar end junction box using a USB power bank. Regarding 12 speed di2, can you mix and match components across 105, Ultegra and Dura Ace? 105 is good enough for me, but I would miss the extra buttons on top of the hoods.

[@Mapdec]

Yes. And upgrading shifters allows you to wire them in and run sprint shifts

[@trevekneebone369]

@@Mapdec Good to know. When my Ultegra 11 speed eventually wears out, I would probably replace with 105 12 speed and Ultegra shifters.

Well balanced review. Spot on.

[@BetterShifting]

I'm pretty sure you know by now (I'm only 11 months late to this party!), but you don't *need* a new PCE02 for 12-speed Di2... just the EW-AD305 adapter or the (crazily expensive new SD300 type link cable). The 'new' PCE02 itself is identical to the one we've been using for years :). Great video either way!

[@Mapdec]

At the time we made this we only had the instructions to go on.

[@BetterShifting]

@@Mapdec what, one year after 12-speed Ultegra and DA release? :) The info was definitely there, also in the Shimano docs…. just spread out over 10 different files. 💩 …That’s why my instructions are better than Shimano’s, easier to read for time-crunched mechanics and users :)

my winter bikes tiagra 10s and its bomb proof. my summer & race bikes are 105 mechanical, im hoping these will last a few years before I need to dip into my pension pot for new kit.
