The Giro Tremor Helmet in Matt Black brings adult trail performance scaled down specifically for growing cyclists. Engineered with Giro’s lightweight In-Mold construction, it permanently fuses a tough polycarbonate outer shell directly to an impact-absorbing EPS foam liner. This creates a highly durable yet lightweight headpiece that withstands everyday trail adventures without straining developing neck muscles.
Temperature regulation is handled seamlessly thanks to 18 channelled ventilation openings designed to channel fresh air across the head during warm afternoon rides or intense pump-track sessions. The classic Matt Black finish delivers a sleek, stealthy look that seamlessly matches any bike setup while naturally hiding everyday scuffs, complete with a removable visor to shield young eyes from sun glare and trail debris.
Achieving a precise fit is simple with the Roc Loc Sport dial fit system, which offers a 7 cm adjustment range for easy one-handed tuning. Paired with Giro’s Universal Child sizing, it adapts seamlessly across growth spurts to ensure seasons of reliable, comfortable head protection.

Before fastening the chin strap, turn the rear Roc Loc Sport dial until the helmet rests snugly and level across your child's head. The front edge should sit roughly two fingers above their eyebrows for optimal forehead coverage, and you should be able to fit two fingers flat between their chin and the strap.
