The RockShox RS SuperDeluxe Thru Shaft RCT rear shock is built for riders who demand precise control and consistent performance on aggressive terrain. Designed around a 230x62.5 mm metric size, it is ideal for modern full-suspension mountain bikes that prioritize sensitivity, support, and durability. The Thru Shaft damper design is known for delivering a more direct oil flow path, helping the shock respond quickly to small bumps while remaining composed on big hits and repeated impacts.
With adjustable rebound and a lockout/firm mode, the SuperDeluxe RCT allows you to fine-tune your suspension for climbing efficiency and descending confidence. The progressive tune is well-suited to many linkage designs, offering good mid-stroke support and bottom-out resistance for enduro, trail, and all-mountain riding. As a RockShox product, it is compatible with widely available service kits and uses proven internal technologies, making maintenance straightforward for shops and experienced home mechanics. Whether you are upgrading from an entry-level shock or replacing a worn unit, this SuperDeluxe model is a robust, performance-focused choice for serious mountain bikers.
