RockShox RCT Rear Shock

A trunnion mount attaches the shock directly to the frame via bolts on the shock body rather than using a traditional eyelet and bushing system. You must ensure your bike frame is specifically designed for a trunnion-mounted shock, as it is not interchangeable with standard eyelet-mount frames.

While the 205mm eye-to-eye length is a critical starting point, you must also match the stroke length of 62.5mm to your frame's specific requirements. Installing a shock with the wrong stroke can cause the rear tire to contact the seat tube or frame linkage at full compression.

The DebonAir spring is designed to provide a smooth, consistent feel throughout the travel that mimics the linear nature of a coil spring while remaining significantly lighter. It offers excellent small-bump sensitivity and mid-stroke support, but unlike a coil, you can easily adjust the spring rate by changing the air pressure with a shock pump.

These independent pistons allow you to tune your suspension for climbing and descending separately. The threshold piston manages the lockout firmness for efficient pedaling, while the open piston handles damping performance for technical terrain, ensuring you don't have to compromise performance in either scenario.

No, the external adjustments for rebound and compression are designed to be tuned by hand using the integrated dials on the shock body. You will only need a standard shock pump to set the initial air pressure for your body weight.

Maxima Plush fluid is engineered to reduce internal friction and minimize damper noise during operation. This results in a more consistent ride feel, especially on long, rough descents where heat buildup can typically cause suspension performance to fade.
