Xlab Avenger TT Carbon the first compact  geometry Tri-Bike, first rear wheel cutout carbon bike.  We believe at 3-athlon.com that when you study the 9 key features, you will not be able to find them all on any other bike.

1. Super-Shift System Faster shifting due to unique Chainstay routing of rear derailleur cable, resulting in a smaller dend radius for the rear shift cable housing.

2. Wind Shadow Rear wheel cutout improves aerodynamics resulting in less drag and faster times.

3. Mega Mono Stay Rear mono-stay shielded from the wind, minimizing frontal area and resulting in less drag.

4. Dual Entry Headtube Minimizes exposed cable hosing and reduces aerodynamic drag.

5. Asymmetrical Full Carbon Aero Fork Flat inner surface minimizes interference drag.

6. Oval Lateral Stiffness Less flex due to a horizontally oversized top tube that gives incredible lateral stiffness and improved power transfer without sacrificing comfort.

7. Power Stays Transfer more of your power to the rear wheel due to oversized chainstays.

8. Carbon Aero Seatpost Low Drag and fully adjustable for optimum saddle position.

9. Quick Change Vertical Dropouts Used on more race bikes than any other dropout design.
