When every curb is a jump and every patch of dirt screams for a skid, the Tremor Mips® is there to keep smiles wide.

The Tremor Mips® model also includes Integrated Multi-Directional Impact Protection System (Mips®), which can redirect energy and provide more protection in certain impacts, providing the latest in head protection technology for junior riders.
Integrated MIPS® Brain Protection System
All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips®-equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts. Learn more about Mips in the video below
In-Mold Construction
In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
Roc Loc® Sport Fit System
The Roc Loc® Sport fit system offers easy one-handed operation with a 7cm adjustment range. Its confident clicking feel and sound lets riders know that the helmet is adjusting to a comfortable fit. With comfort similar Roc Loc® 5 and ponytail compatibility, the new Roc Loc® Sport fit system brings premium function to sport level helmets. Versions with the Integrated Mips® Brain Protection System may provide an additional measure of protective capability in certain impacts.
