Felt built its name by creating innovative, aerodynamic bikes to race against the clock. For more than 20 years, they have continually brought new ideas to rider positioning, efficiency and, above all, aerodynamic performance. From World Champion triathletes , and Terenzo Bozzone, Olympic and World Time Trial Champion Kristin Armstrong, to the pros of Argos- Shimano, when it comes to solo efforts, winners rely on Felt. The bikes you see in the Felt 2013 TT/Tri Series have undergone years of development refinement and have already been proven-in the wind tunnel and in competition-to be there fastest yet. The B Series bikes, which are continuously recognized by cycling magazine editors for their blend of incredible performance and value, have been updated to improve performance across all price points. Both the B2 and B12 frames are descendants of the DA frames, with nearly identical shaping. Engineers tweaked the front end to accommodate the standard fork, giving the headtube an aero and torsionally stiff hourglass shape. The result is a frame with ProTour calibre performance.
