Assos - RAPIDFIRE Chronosuit S11 - Men's - White Series

The RAPIDFIRE S11 is the ultimate race-day skinsuit - purpose built for the time trials and track racing with zero compromises. 

Designed with WorldTour feedback from Tudor Pro Cycling and Swiss Cycling, and validated in the wind tunnel, it delivers maximum aerodynamic efficiency, targeted compression and ultralight breathability. 

With no storage pockets, a transparent number window and an internal radio slot, the RAPIDFIRE is engineered for one goal, pure racing performance.
