2012 Jamis Comet
Comet might be our entry-level tri/TT bike, but it’s hardly entry-level in its performance. Our full-carbon Windshield fork, which shields its rear-facing brake with a slick aero profile, is the same one fitted to our awesome Xenith T-series frames. And the chainstay-mounted rear brake and rear-entry dropouts let the rear wheel snug right into the wheel-cut seat tube for maximum aero efficiency and minimal drag.
Click into the pedals, get that FSA Gossamer crank churning, and power down the road with your fingers flicking the microSHIFT levers through all 20-speeds of the Shimano 105 drivetrain. This is what TT performance is all about.
