RockShox Deluxe Ultimate RCT 2025 Rear Shock

Light on ounces and heavy on capability, Deluxe Ultimate adds a touch of luxury to the latest uber-capable trail bikes. From the new DebonAir+ air spring that offers more volume tunability than ever to the damper’s independent Low Speed Compression and Rebound adjustments - every aspect was carefully designed to maximize tunability into a streamlined, minimalist package. The power is in your hands to dial in the perfect-for-you, perfect-for-the-trail-ahead settings. A custom-tailored ride, every time.

Technology

Metric Sizing

Metric sizing allows both suspension and frame manufacturers to simplify rear shock sizing and fitmen in addition to increasing bushing overlap, which results in better traction and improved durability.

Maxima Plush Dynamic Suspension Lube

Maxima Plush Dynamic Suspension Lube reduces friction, lasts longer, and enhances suspension performance ride after ride.

DebonAir+

DebonAir+ is built to strike the perfect balance of what riders really want: butter-like small bump feel, increased support throughout the travel, and higher overall ride height for more confidence when things get steep.
