RockShox Super Deluxe Ultimate RC2T Rear Shock (D1)

Super Deluxe Ultimate combines race-proven performance with a highly tunable platform, making it adaptable to a wide range of frames and riding styles. Built for everything from downcountry to enduro, it delivers consistent control and responsiveness across varied terrain.

The LinearXL air spring provides a predictable, coil-like feel with improved support through the stroke and a revised bottom-out system for confident end-stroke control. The updated RC2T damper features intuitive high- and low-speed compression adjustment, while a redesigned main piston tune aligns performance with Charger 3.2 characteristics for improved mid-stroke support. With increased maximum pressure capacity and refined internal damping, Super Deluxe Ultimate delivers smooth, controlled performance for a broad range of rider weights and conditions.
