Giro's entry helmet for racing cyclists has the features and design of the top models. The slim helmet shell is light and has 21 ventilation openings. Three available tray sizes combined with the Roc Loc 5 adjustment system provide a good fit.
Roc Loc 5 Fit System The new benchmark for fitting systems is without a doubt the Roc Loc 5 fitting system. The adjustment mechanism is in a mini housing, meaning size adjustment can be easily done in small increments with two fingers. In addition, the system can be adjusted in height to ensure a perfect fit of the helmet.
Wind Tunnel Ventilation Wind tunnel ventilation is Giro's own system of internal ducts and active ventilation openings that direct cool, fresh air over and around your head, squeezing out the exhausting heat and stale air. A difference you can see and feel on every ride.
