The Swiss bike maker has jumped head first into triathlon with this highly integrated multisport machine with moderately-aggressive true triathlon geometry.
The all-new BMC TM01 that was ridden to an iron-distance world record and Tour de France win this past summer will be available to mortal athletes in January. Although it is best known as Cadel Evans’ time trial bike, the TM01 is clearly a triathlon bike and not simply a TT bike relabeled for sale to triathletes. In fact, BMC actually had to make a custom aerobar attachment system to accommodate Cadel’s radically low aerobar position because the frame itself is designed for the taller positions typically ridden by triathletes. In addition to the triathlon-friendly and highly adjustable geometry, which BMC has labeled P2P (power to perform), the TM01 has a long list of features designed to minimize the aerodynamic drag created by the frame.
The TM01 is built in four frame sizes, three of which have stack and reach values similar to the Cervelo P2 and would be considered to have a “moderately aggressive” geometry. The fourth frame size, however, is a match for an entirely different riding style.
The three primary sizes—S, M-L and L—have stack and reach values that fall between the Trek Speed Concept and the Cervelo P4, almost on top of the Cervelo P2. BMC Road Product Manager Andrew James says the TM01 was designed as a triathlon bike, not a time trial bike, and this geometry scheme supports that assertion. The fourth frame—size M-S—has the same reach value as the M-L, but a substantially taller stack value. This specific frame is one of the most geometrically conservative—read: upright riding position—triathlon bikes sold today. The M-S size is even more unusual it builds conservative geometry into BMC’s flagship tri bike. Almost all other top-end tri bikes are designed with long reach values and short stack values to accommodate very aggressive positions. This bike is uniquely suited to the athlete that wants a pro-level frame but simply can’t fit a pro-style position. Since BMC is only producing a single frame size for this riding style, however, only athletes that fit this one model get to make that decision.
The seat post has a true 77-degree angle, but the saddle clamp can be moved forward 21 millimeters. James says Andreas Raelert rides with an 82-degree effective seat tube angle. By using a standard aerobar instead of an integrated unit, the TM01 is able to morph its geometry by selecting a bar that complements the rider’s fit preferences rather than being constrained by the dimensions of a proprietary bar.
