When every curb turns into a jump ramp and every patch of earth screams for a skid, the Tremor is the perfect companion to make a wide grin even wider. Equipped with some of the great technologies from Giro's adult line, such as In-Mold construction for less weight and better durability, as well as the popular Roc Loc Sport adjustment system for quick, secure helmet fitting, the Tremor is ready for action at any time.

This fusion process allows for better ventilation systems, making In-Mold helmets lighter and cooler than traditional helmets. Intended use: MTB. Certification: EN 1078. Weight: 260 g.
