The First is RST's workhorse XC fork, lightweight and packing the performance you want at a budget friendly price. Featuring a stiff while still being lightweight 32mm chassis the First is ready for whatever you want to throw at it. It uses a proven AIR spring system which has a air over coil negative spring and uses in-leg XC optimized OCR damping system which has external compression adjustment with lock-out and rebound adjustments. It can also be equipped with an optional remote TRL remote lock-out lever.
The OCR System (Open-bath Compression Rebound Damping) offers a fully adjustable hydraulic compression damping with lock-out, as well as externally adjustable rebound. This technology has been race proven and refined on the world circuit.
An air spring is used to achieve maximum performance as well as saving weight over using a steel coil spring. With air you can achieve an infinitely adjustable spring rate that feel much more natural and sensitive than a traditional fork.
