Record-shattering speed is yours with Zipp’s wind-cheating 900 Tubular Track Disc. Extensive wind-tunnel testing and countless race victories prove that it excels in all conditions. Zipp's dimpled carbon surfaces further smooth airflow, while an amazing un-disc-like weight of just 935 grams lets you accelerate like a jackrabbit on a sugar IV drip! Zipp's Carbon Bridge technology weaves Kevlar threads into the rim’s contact surface for excellent strength and longevity, while Zipp’s hubs are built with precision bearings and oversize axles for super-low rolling resistance and maximum power transfer.
