Description
FEATURES:
- Extensive testing in the A2 Wind Tunnel produced a host of frame and fork refinements that allow the wind to flow over the bike with minimum drag.
- 800K high-modulus carbon fiber has a groundbreaking weight-to-stiffness ratio; its used to construct a frame that is stiff for maximum pedaling power, yet comfortable enough for Ironman distances.
- New rear stays are shaped to fit all the commonly available deep-dish and disc wheels while preserving aerodynamics.
- New vertical dropouts combine a secure hold with 8mm of fore-aft adjustment to get the rear wheel in the perfect aero position.
- Geometry is ideal for the demands of long-distance triathlons. A slightly taller head tube allows a more upright position to keep the legs fresh and strong for the run stage.
- TRP 920 Forged Aero Center Pull braking system offers superior aerodynamics and easy wheel changes.
