Nitron R1 Caterham- Esteemed by drivers around the world, NTR R1 kits provide the answer to uncompromising quality, reliability and performance without the need for a remote canister. Fade-resistant and hand built with ultra-low friction components, the R1 shock is made to last on the road and track. The high-grade materials protect against corrosion whilst significantly reducing weight. Every R1 kit is custom built, sprung and fully serviceable. A double-acting single dial delivers effortless control over wide-ranging damping adjustments; allowing the vehicle to rapidly react and adapt to changing road and circuit conditions. Titanium and hard-anodized parts are hand built to last not only the lengthiest endurance races but also the harshest of winters. Note:Image used for illustration purposes only.
