The Rock Shox Rear Shock Super Deluxe Thru Shaft RCT (230X57.5) is engineered for riders who demand exceptional performance and reliability on challenging trails. Designed for the Remedy and Slash models from 2017 to 2020, this rear shock offers a perfect balance of control, comfort, and responsiveness, enabling you to push your bike to its limits with confidence. Its black finish and asymmetrical Trunnion/Yoke design ensure optimal frame integration and rider ergonomics, creating a seamless connection between your bike and the terrain.
Featuring Trek's exclusive ThruShaft technology, this shock reacts faster to changes in terrain than traditional designs, delivering a smoother and more controlled ride. The RCT damper offers finely tuned rebound and compression adjustments, including a 380 lockout, giving you the ability to customize your suspension precisely to your riding style and trail conditions. Whether you are tackling technical descents or climbing rough ascents, this shock provides consistent performance thanks to its oversized thermal compensator that stabilizes temperature and maintains damping consistency over long rides.
Installation is simplified with the Trunnion mount and Yoke eyelet, tailored specifically for the Remedy and Slash frames. Although hardware is not included, this shock is compatible with purple tokens for adjusting positive and negative air spring pressures, allowing further tuning options. The Super Deluxe Thru Shaft RCT is a robust and versatile upgrade that will elevate your mountain biking experience, combining cutting-edge technology with durable construction to withstand the rigors of aggressive trail riding.
