Cushcore 70021 Rim Unisex Adult Cycle Helmet, Grey

An ultra-lightweight insert that reduces fatigue, improves cornering, and helps prevent flats. CushCore is no ordinary tyre insert and is based on a new concept, tyre suspension. Any suspension system has a spring and a damper, and with CushCore, pressurised air in the tyre is the spring and the CushCore tyre insert is the damper. Go Bigger CushCore improves suspension performance by 16% and reduces impact force from big hits by 50%. Send it with total confidence. Corner Harder 35% more sidewall stability eliminates tyre squirm and burping, even at low tyre pressure. Rail corners with total confidence. Ride Faster CushCore provides a 12% smoother ride and 3% reduced rolling resistance. Ride with more control, more momentum, and less fatigue. It's like taking fewer punches in a fight.
