Genuine RockShox Crown-Steerer-Upper Assembly

Rebuild your suspension system with the RockShox Crown-Steerer-Upper Assembly for Lyrik B1/C1 and Yari A1/B1 DebonAir forks. This genuine replacement part ensures factory-level precision, stiffness, and alignment, restoring the smooth, responsive feel RockShox forks are known for.

Built for 15x110 Boost spacing and 42mm offset, it’s engineered to maintain perfect damping control and front-end tracking under aggressive riding conditions.

Precision Fit for Peak Suspension Performance

This Crown-Steerer-Upper Assembly replaces worn or damaged upper units while preserving your fork’s geometry and steering accuracy. CNC-machined for optimal strength-to-weight ratio, it maintains structural integrity even under heavy trail loads and repeated compression cycles.

For proper setup and maintenance, use suspension tools to ensure correct torque and seal seating, and shock pumps to fine-tune air pressure for your DebonAir spring system.
