Deluxe Ultimate RCT Rear Shock - 210x52.5mm C2

The RockShox Deluxe Ultimate RCT Rear Shock (210x52.5mm C2) redefines what a lightweight inline shock can do. Built for riders who demand both precision and plushness, it brings together the control of a custom-tuned system with the reliability and smoothness that mountain bikers trust from RockShox. Whether hammering climbs or dropping into technical descents, the Deluxe Ultimate RCT keeps traction dialed and performance consistent, mile after mile.

This version features the updated DebonAir+ Linear XL air can, designed for a broader tuning range and more responsive small-bump sensitivity. Paired with independent Low Speed Compression and Low Speed Rebound adjustments, it gives riders the ability to fine-tune every aspect of their suspension feel. The bottom-out control system keeps things composed on big hits, while the Maxima Plush damping fluid ensures smooth, quiet operation through the roughest terrain.
