Giro Radix MTB Helmet Grey S

(84 reviews)

A super-light modern trail helmet - that's the Radix. The shape of the helmet is literally chewed to the bone - no design frills and frills on the viewer. Simplicity is power! The comfort and level of protection will give you confidence even on day-long expeditions into technical terrain. A perfect fit on the head is ensured by the Roc Loc 5.5 clamping system, which you can adjust to your exact needs. In the case of the variant with MIPS technology, it is also integrated with the MIPS insert. MIPS technology available in selected colours. MIPS (Multi-Directional Impact Protection System) provides increased protection against rotational forces on the head.
