BMC Road Machine One and Di2 12 speed Review
These are just my personal observations and opinions- I am a decidedly average bike rider in my sixties. I recognize other people will feel differently, so take what I say with a grain of salt.
Last winter I was looking to upgrade from my 2015 Giant Defy Advance 11 spd mechanical ultegra. I really like the bike, but I had watched too many GCN videos and was feeling that I wanted to get a bike with thru axles and hydraulic disc brakes.
Went to my LBS where I purchased the Defy and they had no bikes- well- that’s not true. He had some low-end bikes and some really high-end bikes that were out of my budget. He did tell me that whatever I decided to buy- it should be 12 speed and electronic because that was the way the industry was going. He also said that unless I wanted to go for a 1X setup, to stay away from SRAM electronic components because he had customers complaining of chain drop.
As I started my search through the various LBS, I could tell that this was not going to be easy due to poor inventory and I had a certain budget that I wanted to stay within, which was going to complicate things even further. First though- I need to find out which frame size was going to fit me. I rode a bunch of different frames (all with mechanical components)- Specialized Roubaix, Specialized Tarmac, Trek Domane, and Trek Emonda. The Roubaix was essential a more road-like version of my Diverge, the Trek Domane was heavy and didn’t quite fit right, and the Tarmac and Emonda felt good, but the geometry’s were a bit aggressive and at age 62 I felt I should look for more of an endurance geometry.
I then stumbled on a BMC Roadmachine with 11 speed Di2- DAMN- the electronic shifting was intoxicating! Lightning fast and so smooth. The 56 cm frame fit like a glove. All of the other bikes would need some adjusting with the stem or handlebars, but the BMC fit perfect. Unfortunately- it was 11-speed and I was looking for a Di2 12 speed. An Internet search turned up a 56 cm BMC One at Podium Multisports in Atlanta (not the One One- just the BMC One- the lower spec slightly heavier bike). I was nervous about not buying from a LBS, but I can’t say enough about Matt and Podium- great service.
I’ve had the bike for 8 months now and gone for rides up to 50 miles-
Things I like:
- As a said before- the bike fits me perfectly. Other than setting the saddle height, I have made zero adjustments and I have never felt uncomfortable during any of my rides.
- I like the fact that the seat tube angle is a little steeper at 74 degrees- I used to do triathlons and I may one day slap a set of aero bars on the bike.
- The bike is stiffer than the other endurance bikes I tested. I actually like that because it gives the bike a very responsive feel, particularly when climbing (which you do a lot of here in Connecticut). However- it might get old on a century ride on poor roads.
Things I don’t like:
- The seat post adjustment is terrible. You can loosen the bolt and you have to bang the seat post multiple times before it will move. My Defy and Diverge are WAY easier to adjust.
- The saddle attachment is also a nightmare. Two bolts and it’s complicated. Again- Defy and Diverge are WAY easier.
- For an expensive bike, I think that they sourced a pretty cheap BB. Unfortunately- it’s press fit, so I am not going to mess with it.
- The steering is not precise- this is hard to describe, but the bike likes to track straight. You are not going to make sharp turns on the bike. I don’t know if this is related to the 71 degree head tube angle or the long stem. It’s also very hard to turn around on a road- it feels like the front wheel is going out from under you.
- The CRD carbon wheels- I was hoping to find a lower spec’d version with DT Swiss alloy rims, but there were not many options out there. I don’t know too much about BMC’s CRD wheels, but the rear hub is LOUD! I mean- REALLY LOUD. I guess this is not a bad thing, because when I’m coasting people can hear me coming, so I don’t have to call out “on your left”. Still- it doesn’t seem like a high-quality hub and for the money, I would have expected more.
Overall, I am happy with the bike. It has some “issues,” and I am sure it is not the best “value” option out there. For me, I think the comfort factor compensates for most of the drawbacks, but I’d probably look at other options more seriously prior to buying another BMC bike (assuming the inventory shortage ever ends).
Now- Di2 12 speed-
What I like-
- Shifts are lightning fast.
What I don’t like-
- With mechanical components there is a physical click when you execute the shift. You don’t get that same physical “click” with the Di2 components. You push the button, but there is no feedback- just a shift (assuming you press correctly).
- Today it was cold and I had to ride with gloves for the first time- I can’t tell you how many times I hit the wrong shifter or just wasn’t pressing the correct spot to get a shift.
- No rear derailleur clutch. The roads where I live can be pretty bad and the chain slap is annoying.
- My initial battery was defective- I was getting about 400 miles on a charge. Podium replaced this promptly through Shimano. I am now getting about 800-900 miles on a charge. I guess that’s good, but I never had to think about a battery level with mechanical components.
- With my mechanical components I could easily make minor adjustments, but I am uncomfortable doing this with the electronic ones for fear of screwing something up.
- IMO- the Shimano app to access the Di2 is not great and could be made more user friendly.
Would I do it again? That’s a tough call. As my LBS guy said- this is the way the industry is going (even 105 is now electronic and 12 speed) and given supply issues, my guess is Shimano is going to prioritize 12 speed over the older 11 speed. That said- I’m sure there will be 11 speed components out there for a LONG time to come. I do miss that solid feedback mechanical components give you, their ease of adjustment, and the fact I can ride them while wearing gloves!
I’m hoping Di2 grows on me, but I may just have to deal with it because I can’t afford to change bikes!

Glad you like your new bike. Apart from a few niggles it sounds like a top machine!
True, but it's easy once you know how. Plus if it helps to ease your concern, in the tens of thousands of miles I've put on 10, 11, and now 12-speed Di2, I can count the number of times I've needed to make an adjustment on one hand.

The one thing that IS worth knowing is the RD's 'crash recovery mode,' in case you ever crash out on the road and need to run through it. I put a note in my phone with the instructions -- they are very simple, but I wouldn't remember in a pinch, since I've not yet had to do it in 3.5 yrs on Di2.

Di2... you won't miss anything about mechanical for long. Reminds me of once when I was getting new ski boots. Talking to the fitter, I said "Well, goodbye to those other boots - I'll kind of miss 'em." The fitter looked at me and said "No, you won't." And she was right.

Couple of things:
-There is a physical click when you press either of the DI2 lever buttons, it's just quieter (and nicer IMO). It's more of a ''tic'' rather than a ''clack''
-Adjustment are in fact very easy to make, but I understand that you may feel uncomfortable given that it's all new for you. The upside is that you should never need any adjustment. No cables = no tension loss = no movement. 10 000kms on my ultegra DI2 and it's never been adjusted.
-Shimano software and user friendliness is indeed crap. Very crappy. There is no mac version of the software either and you have to purchase a D-FLY unit to make it bluetooth. SRAM is a lot better.

Nice review... I recently got a Roachmachine Three and upgraded the wheels and cockpit. Easily my favorite bike (and I've had a lot of different ones). Di2 is phenomenal. Makes even Dura Ace 9000 seems slow, which is saying a lot.

Geez, that’s a bummer review! Sorry to hear it. A bike that handles poorly, you can’t operate the shifters accurately with gloves, and you get annoying chain slap. I guess disliking the freehub sound and having a pain in the ass seatpost are rather crummy, too, but worse is that, glove issue aside, after 8 months of riding you’re not in love with Di2.
Too bad your LBS gave you a bum steer on Sram, because an AXS groupset would have solved a few of those problems, and you’d have a friendlier adjustment interface for easy tweaking, too. You’d also have no wires, which would open the door to an easy frameset swap ( as a solution to the poor handling).
You may want to consider selling this rig now, as the secondary market is strong these days. And, at 60 years old, it probably makes sense to move-on soon in that regard as well.
Anyway, good luck. It’s a tough spot to be in, not loving your bike. I was there for awhile after a couple of bikes were stolen at university, and I remember how it felt. I didn’t like it.

Thanks
Thanks to everyone for input regarding the Di2. I’ll definitely check out online videos for making adjustments, although it sounds like I won’t need to worry about it. The crash recovery mode is something I’ll definitely look into.
Sorry if the review came across too negative. I’m actually fine with the bike. Just giving my personal opinion now having been on the bike a while. Other people will probably have different things they like and dislike. Some web site reviews are good, but others don’t seem reliable. I’ve rode a couple of thousand miles now and felt I’d put my impressions/observations out there.
At my age- I’m hoping this is the last bike I’ll be looking to get!
Thanks again!

Anyway, sounds like your BMC and Di2 setup is a bit of a mixed bag. Hope it gets better for you!

The hub noise, adjustments, pressfit bb, etc all feel superficial compared to the poor handling complaint.
I can't imagine spending this kind of money on a road bike and feeling like the steering was not precise, or that the bike was hesitant to turn in on corners, or that the front end is going to slide out.
I realize the Roadmachine is BMC's "endurance" geometry, but a road bike like this should still make you feel like you can rail corners if you want to.

There's nothing about the geometry that would cause poor handling or turning. Be sure that the headset isn't too tight or too loose. The seat post wouldn't have enough set back for me. A loud rear hub most often needs more grease or a heavier grease around the pawls.

Update on the BMC. I've had the bike for about 1.5 years now and gotten in a few thousand miles. I upgraded the wheels to Roval Alpinist and the bike was literally transformed! Absolutely love the ride. I think my feeling of the slow steering was related to the long stem. I've not had a bike with a stem as long as on the BMC, but I've learned to adapt to it and no longer have any issues with the steering (it feels more precise). I still don't like the Di2 when it's cold and I'm wearing thick gloves, but otherwise I have come to really enjoy electronic shifting. Overall, I'm very happy with the bike.
