FeaturesAll Aero tubing profiles, rear-entry dropouts, wheel-cut seat tube, and chainstay mounted rear brake all contribute to make the Comet the fastest bang for the buck in the Tri world. Our revolutionary full carbon monocoque WindShield fork encloses the front brake within the fork blades for superior aerodynamics, with easy-access brake ports to simplify brake maintenance. Alex RA30 rim with 30mm aero profile, Formula smooth spinning hubs (20/24H) and Formula bladed stainless steel spokes make a great all-around wheelset is light enough to be used on race day and durable enough to provide lots of carefree training miles FSA's Gossamer crank features a MegaExo integrated BB which eliminates bottom bracket flex via an oversized BB spindle and offers oversized external bearings for additional durability and strength. The full size 53/39 chainrings deliver the highest possible top end speed and hopefully a personal best split. Tektro's TT-specific brakeset offers a more compact shape for improved aerodynamics, with cartridge SwissStop pads for superior braking performance. A complete Shimano 105/Ultegra/Micro Shift drivetrain assures light, precise shifting over all 20-speeds. Profile Design's T3+ drop-bend, Air Wing base bar and Aris stem cockpit offers complete adjustability and comfort in a surprisingly lightweight package. Vittoria's Zaffiro 23c tires deliver legendary road holding capability and ride quality. Comet features the same carbon aero seatpost as offered on all our Xenith T-series.
