BMC's new TM01 bike is a stunning sight to behold.

One bike that has made a lot of headlines in the tri world is BMC's new TM01. The bike debuted at the Dauphine de Libere just prior to the 2010 Tour de France. The bike incorporates many of the aerodynamic cues we've seen elsewhere in the triathlon world -- truncated airfoil tube shapes, integrated front and rear brakes -- etc. But the BMC does them very smartly. When they integrated the front brake, they rightly made it a centerpull design, so that there was no nasty cable hanging out in the wind, a la Giant Trinity and the new Argon 18. And with all the integration this bike offers, BMC kept room for a lot of modularity. The stem is a round clamp, so you can use any standard aerobar. The bottom bracket is BB30, so you can use nearly any crankset (including one of my favorites, the Lightning). And the bike is designed to work with the new generation of ultra-wide rims. In fact, the version of the bike that I test rode comes stock with the fantastic Zipp 808 Firecrest wheelset. It's also equipped stock with Shimano's Dura-Ace Di2 groupset. Not a bad spec!

Test Ride Verdict: I want more

This bike does a lot of stuff right - just check out the sick nude carbon paint scheme!

When BMC offered me to test ride the brand spankin new TM01, I couldn't resist, and wanted to take a few photos to boot. I have to reserve full judgment on the bike until I can take a longer look at one, since we didn't have enough time to adjust the bike's front end to my position.

But I can say one thing for sure - this bike is mean. I'm very, very curious to see this bike some more. And hopefully it won't be too long before I can get one to test - BMC says this bike is shipping to stores in just a couple months. For now, enjoy the gallery.

UPDATE: I had a chance to shoot a video with Andrew James, the product manager for BMC, on the showroom floor at Interbike. Andrew went through some of the tech/marketing language that BMC is using about this bike. Specifically, they like to say that a rider's maximum velocity is achieved with their new bike through a combination of optimal bike adjustability and superlative aerodynamics. Or in their lingo, Vmax = p2p x subA. Whatever you happen to think about the marketing jargon, the video gives you a good sense of the landscape of the new Timemachine TM01.


  • This is the high-end TM01, spec'ed with Shimano Dura-Ace Di2 and 808 Firecrest wheels.  The Dash saddle and Aerolite pedals are mine, but the rest you see here is stock.
  • BMC confirmed that the TM01 will have a BB30 bottom bracet, so riders will have the option of putting on some very snazzy cranks like the Lightning, etc. This one had a threaded adapter in place so it could use Shimano's Engish-threaded BB.
  • One thing I LOVE about this bike is that BMC gave it a very minimal paint job, exposing a lot of nude carbon.
  • Very skinny from the front, with no nasty brake cable hanging from the sides.
  • The front brake cable enters through this port at the top of the headset area, keeping it minimal but still easily serviceable.
  • The BM TM01 is already UCI approved.
  • The seatpost is held in place by a minimal clamping wedge that actually sits inside the top tube, and gets covered by a rubber grommet.
  • Of course, I brought my Dash Tri.7 along for the test ride. The BMC has a single seatpost with multiple fore-aft adjustment options. The saddle adjustment is slightly tricky, as you have to wiggle a wrench under the saddle shell but over the rails.  Fortunately, the Dash saddle has room, and getting a wrench in there is no problem.  Other saddles might be harder to adjust.
  • The adjustment at the rear dropout is much like that of the Cervelo P4 - a thumbscrew give you fine control over the rear wheel gap.  The Di2 cable comes out at the same spot for a very clean routing.
  • BMC integrates the rear brake into the TM01's bottom bracket.
  • Viewed from below, you can see there's no cover for the brake, making it easier to service.
  • We're not sure whether there's full housing inside the frame, or cable stops.  Must investigate further.
  • Cables enter the top tube from this little access port, and the bike comes in both Di2 and cabled versions.
  • Little stops on the top tubes imit the steering radius to what you see here, which should be more than enough, but you can't turn any farther than this.
  • The rear stays, like the rest of the bike, are angular and stylized.
  • The Di2 version has a hidden battery, which is actually bolted to this cover.  So when you unscrew the cover, the battery comes out right along with it - no fishing required.
  • Another shot of the rear dropout and thumbscrew.
