BMC Switzerland and Campagnolo Srl have unveiled the AG2R Citroën Teammachine SLR01 for the 2021 WT season. Check out a beautiful video of the bike being built:

Beautiful bike... Mechanic appears to be hating life.

Hi, new to the forum and found this thread. Wondering if anyone can confirm that they were able to mount the 2021 Teammachine to a trainer and if so which one? I live in Canada and purchased a Teammachine SLR Three in November. Snow has prevented me from riding outdoors and I am unable to use my old trainer with the bike.
Thanks,

Does anyone have more detailed information regarding the ICS Carbon?
Geometry, weights, information regarding stiffness.

I did find a build up video on youtube, where the unspecified Cockpit weighs 332 gr....not sure which size. Excluding fork wedge and topcap. Bit dissapointing, but anyway. https://www.youtube.com/watch?v=I7NHLP5mYBE&t=92s

Someone already having some experiences with the cockpit?
Interested in buying Carbonsport Lightweight wheels with broken spokes.

As far as I know, you can only use an indoor trainer which has native thru axle support like the Wahoo Kickr or Tacx Neo 2T. There's no solution for a wheel-on trainer or a direct drive trainers that require adapters + QR Skewers like the Tacx Neo/Flux.

Hi Everybody,

I'm new here and looking form information on the new BMC Teammachine...
I already own a '19 Teammachine SLR01 disc and going to buy another one, but '21 model.

Looking at the details in geometry tables & components specifications I'm a little bit confused about the new ICS carbon cockpit.

According to the specs on BMC site the new cockpit handlebar has 67mm reach, which is very short. In fact one of the shortest I've ever seen.
Second, I can't find anywhere if the stack of the integrated stem is the same as the ICS01 stem (about 48mm).

Can anyone that owns this model confirm the measures for the handlebar?

My current setup is: frame size 51, shimano shifters,100mm stem, 420mm 3TErgonova handlebar with 77mm reach, no spacers installed.

According to the reach difference in the handlebar I'm considering a 110/420 ICS carbon cockpit for the new bike....
But the new cockpit is crazy expensive so I want to be 100% sure!


For the new bike:

1. still in doubt about the specification on BMC site (it would not be the first time that an error appears in the official specs)
2. i will install sram axs shifters on the new bike: are those longer than Shimano DA 9170?


Thanks to everyone who will help me,
Ciao!

Thanks for the response. I'll try to pick up a Kickr.

That's one hell of a beauty.. Really nice colour combo in this photo as well. :thumbup:

But but, the water bottle kind of spoiled it for me; I think this bike can use some different looking ones. :beerchug:

You're welcome! I hope you understand I cannot comment on any information that has not been released by BMC Switzerland.
Great to have you post here. I was wondering if you can talk generally about the aerodynamic modeling process you used. I recall on an earlier version of the Team Machine there was little wind tunnel testing done but lots of heavy simulations to optimize the aero profile. I am curious whether you guys continued with this approach on the latest release. I've had the opportunity to meet Cadel Evans through friends a few times, and I found it quite refreshing how much emphasis BMC appeared to put on the comfort aspects of an all out race bike, as I think these matter even more to those of us who are normal as opposed to pro riders.
Lots of bikes: currently riding Enve Melee, Krypton Pro, S Works Crux, S Works Epic Evo, SL7.
In build: SW SL8

Hi! I can talk a little bit about it, but I cannot go into great detail. Implementation of aerodynamics in bikes has been getting more and more important over the past years, and this is of course the same at BMC.

The approach for the Teammachine SLR has always been that it has to offer a well-balanced blend of performance characteristics for riding in a WT-peloton. Those performance characteristics used to be power transfer, comfort and weight. These were used in the ACE-technology that was introduced about 8 years ago to determine the optimal balance between tube shape, fiber type and strand orientation.

For the fourth generation Teammachine SLR, we added aerodynamics as a fourth variable in the ACE-technology, naming it ACE+. The way this works is that a simulated aerofoil section that's measured to be the fastest section in a 3 to 1 tube ratio (measured head on and at several yaw angles) is implemented as a fixed ratio shape for certain tube sections. This shape was first heavily implemented in the Timemmachine Road (MY2019), but the Timemachine Road was not designed to be the lightest bike it could be. Simply the fastest road bike in a sprint or breakaway, in a racing situation.

The instruction is that the fixed ratio of the aerofoil section is forced to be used in a few tubes on the fork and frame. However, both the size (if X changes, Y changes the same amount) and the location of the trailing edge measured from the leading edge (which truncates the aerofoil) are not fixed. ACE+ combines these inputs (plus a desired fillet size on the sharp edges of the profiles, from a weight point of view) and gives the optimal tube shapes.

All BMC racing oriented bikes are designed to be a solution to the challenge of achieving the highest average speed in whichever one day, stage race or crit race it is used in. One of the key priorities for achieving the highest average speed (and thus winning the stage or the race) is to maintain rider efficiency throughout the race. Vertical compliance reduces the transfer of road chatter into the muscles of the rider, which saves the muscles for the job of propulsion.

Now of course, a more leasurely-rider (such as myself!) also benefits from a compliant bike. It doesn't just add free miles to the same effort, it also makes for a more relaxing experience obviously.

In the end, bikes that are released have been in development for a few years before you see them. Meaning that by the time you read this, the way these bikes come together from an aerodynamics point of view is already partially redundant. So don't lean too much on what you read here as the blueprint of how other BMCs are developed.

I hope this answers some of your questions! Please bear in mind that I no longer work at BMC and that these are just my personal opinions and interpretations.
