Giro Trinity Helmet - Black/White - 54 cm - 61 cm
Sometimes the simplest designs are also the smartest. The Trinity™ is an easy fit for riders who want a classic cycling helmet that doesn’t compromise comfort or performance. It includes key features like In-Mold construction to keep the weight low, and the easy one-handed adjustments of our acclaimed Acu Dial™ system for a quick, sure fit no matter where or how far you ride.
Acu-Dial The Acu Dial system combines single-handed adjustment with a full fit band that brings a quick, sure, ponytail-compatible fit in Giro's line of Universal Fit helmets.
In-Mold Construction In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.
