The RockShox Festkolben Monarch Plus/RL/XX (B1)/R/RT/RT3 (C1) is a high-performance rear shock component designed to restore or upgrade the heart of your Monarch Plus suspension. Built around RockShox’s proven air shock platform, this part is intended for riders who demand consistent damping, reliable small-bump sensitivity, and strong mid-stroke support on demanding trails. Whether you ride aggressive trail, all-mountain, or light enduro, it helps your rear suspension track the ground more precisely, improving traction, control, and comfort on rough terrain.
This Festkolben unit is tailored to work with various Monarch Plus and Monarch RL/XX/R/RT/RT3 generations, making it ideal for servicing a tired shock or completing a detailed rebuild. Using high-quality seals and precision internal components, it is engineered to reduce friction and maintain smooth performance over long periods of riding. By refreshing your shock with genuine RockShox internals, you can restore factory feel, improve responsiveness, and extend the life of your suspension, all while keeping the familiar tuning range and adjustability that Monarch shocks are known for.
