2011 Jamis Xenith T Carbon Triathlon Bike – XS 650c Chromium Frame

Advanced Road Racing Bike: Precision Engineering for Elite Performance

Engineered for competitive cyclists seeking maximum aerodynamics and lightweight efficiency, this advanced road bike combines cutting-edge materials with refined design to dominate on race day or training routes. Designed for riders 4’10” to 5’3″ (XS size: 48.5cm effective top tube), this machine balances power transfer with precision handling for optimal performance in high-speed scenarios.

Frame Technology
The full aero carbon monocoque frame features internal cable routing for sleek aerodynamics and reduced maintenance while maintaining structural integrity. Chainstay brake mounts enhance control on descents, while airfoil-shaped tubes minimize drag at race speeds. BB30 compatibility ensures seamless integration with modern crank systems, and rear-entry dropouts simplify wheel changes during pit stops.

Propulsion & Control
Shimano Ultegra rear derailleur paired with 105 front derailleur delivers precise shifting under load, complemented by Dura Ace shifters for intuitive gear transitions. The FSA Gossamer BB30 bottom bracket enhances power transfer efficiency, while the 52/38 chainring setup balances climbing ability with sprinting responsiveness. TRP T725 aero TT brakes with Swiss Stop dual compound pads provide exceptional braking power in varied weather conditions.

Aero-Optimized Components
The Alex A-Class ALX-320 wheelset features 20/24H lacing and sealed cartridge bearings for low rotational resistance and durability over long miles. Vittoria Zaffiro Slick tires (or Rubino 650x23c for 47cm wheelbases) offer low rolling resistance and reliable grip on smooth surfaces.

Ergonomic Precision
The Profile cockpit system includes T1+ extensions for aggressive riding positions and T2 Wing base bars for stability during sprints. The Xenith T Aero post adjusts seamlessly for custom fitment, while the Selle San Marco Ponza TT saddle prioritizes comfort during high-intensity efforts.
