Giro Helmet Roc Loc Fit Systems
Biking isn’t a static sport. That sounds obvious, but the reality of it can hit you upside the head sometimes. In fact, it used to do that all the time. Before Giro invented the Roc Loc® fit system in 1994, mountain bike riders were simply accustomed to their helmets rattling down the trail.
You’d find yourself hurtling through the chunder at Mach Chicken with your helmet bucking around on your head— an annoying, rattling, sweaty, party crasher. As the first fit system to truly allow you to fine tune helmet fit, the Giro Roc Loc® tamed the beasts atop our heads. It was a complete game changer.
The Giro Roc Loc® greatly improves a helmet's stability when riding over roots and rocks. Jokes about jock straps ensue, but soon every Giro helmet has one.
