Jamis Comet (2013)

The clock is relentless. So are we. Which is why we’ve pored over every millimeter of our Xenith and Comet TT and Tri bikes—because you deserve to squeeze every bit of speed from every milliwatt you can muster up against the clock.

The Windshield aero fork with rear-facing/fully-enclosed front brake, NACA-compliant aero profiles throughout the frames, the rear brake snugged under the chainstays and a seat tube shroud shielding the rear wheel, all combine to ensure that these frames slip through the air like a greased arrow.

An aggressive 78-degree seat tube angle and a 46mm bore PF30 BB system (on the Xeniths) help you maximize your power as you churn those gears. And we’ve given these bikes head angles and fork offsets that work like a charm with TT bars for straight-line stability in an aero tuck and sizzling-fast cornering manners on technical courses and at turnarounds.
