RA Cycles carries road bike helmets, aero and triathlon helmets, mountain bike helmets, and youth helmets from Giro, Kask, MET, Lazer, Bell, Oakley, Scott, and Mavic. The road lineup runs from everyday training helmets with high ventilation — the Giro Helios Spherical, Giro Eclipse Pro Spherical, and Giro Aries Spherical — up through Kask's Protone Icon and Elemento, which cover the premium road and climbing range. For aero and triathlon, the Giro Aerohead MIPS, MET Trenta 3K Carbon, and MET Manta MIPS offer wind-tunnel-developed drag reduction with varying levels of ventilation depending on conditions and race format. Mountain bike helmets include both trail-open and full-face options — the Giro Montaro MIPS III and Bell XR Spherical cover the trail and enduro range. Most helmets in this collection include MIPS rotational protection as standard.
Not sure which helmet fits your discipline or head shape? Our team can walk you through fit system differences, MIPS vs. non-MIPS tradeoffs, and ventilation comparisons across road and aero models.
