MRP Ramp Control Cartridge - Mountain Bike Fork Cartridge Upgrade

The MRP Ramp Control Cartridge is a game-changing upgrade for your mountain bike fork, allowing on-the-fly tuning of your suspension’s end-stroke performance. Unlike traditional volume spacers, the Ramp Control Cartridge lets you adjust bottom-out resistance with a simple 16-position dial—no tools or workshop required. This speed-sensitive cartridge isolates big-hit performance while leaving the fork’s initial and mid-stroke unaffected, offering unparalleled adaptability for varying trails and riding styles.

Key Features:

• On-trail tuning: Adjust end-stroke support easily with a 16-position dial.
• Velocity-sensitive control: Adds speed-sensitive bottom-out resistance for intense impacts like drops and rock gardens.
• Lightweight design: Weighs approx 55g, lighter than most air-spring assemblies with more than two tokens.
• Versatile performance: Fine-tune bottom-out resistance without compromising initial or mid-stroke performance.
• Quick installation: Installs in minutes with basic tools—no need to remove the lower fork legs.
• Improved adaptability: Easily adjust for varying terrains, from bike parks to steep downhill courses.

With the MRP Ramp Control Cartridge, you can ditch the trial-and-error of volume spacers and tune your suspension precisely to the terrain, ensuring peak performance for every ride.
