Whether it’s sprint or endurance events, there’s no room for error on the track, and developing bikes for World Champions like Sarah Hammer and elite track teams like Project London keeps Felt on the cutting edge of technology. In track racing, it’s one bike, one gear—and the results don’t lie. Like the DA time trial/triathlon bike, the TK1 uses Felt’s UHC Ultimate+Nano carbon fiber, unsurpassed for its ability to make lightweight, stiff, ride-tuned performance bikes. Just as with the DA, the TK1 was engineered using powerful, cutting-edge CFD software and extensive aerodynamic analysis. Once the materials were chosen, Felt engineers applied proven geometry to give the bike precise, track-specific handling characteristics.
