Ultimate RCT Trunnion Rear Shock - 185x50mm C2

The RockShox Deluxe Ultimate RCT Trunnion Rear Shock (185x50mm C2) delivers the kind of precision, control, and refinement that serious riders demand when chasing the perfect line. Built around the DebonAir+ Linear XL air spring, this lightweight inline shock gives riders the full range of tuning options to match their terrain, style, and speed. Whether you’re hammering through rooty descents or grinding up technical climbs, the Deluxe Ultimate RCT keeps the ride composed, efficient, and whisper-quiet.

Every detail of this shock is designed for optimized trail performance—from independent low-speed compression and rebound adjustments to a bottom-out system that enhances control when things get rough. Add in Maxima Plush damping fluid for ultra-smooth operation and noise reduction, and you’ve got a rear shock that feels as good as it looks.

Key Features:

• DebonAir+ Linear XL air can offers wide-ranging tuning potential in a compact, responsive design.
• Bottom-out system provides a more open compression feel for better control and reduced harshness.
