Ohlins

Crown Stanchion Unit, 44mm, RXF36, Evo, M.2 29"

Ohlins Crown Stanchion Unit (CSU) is the correct factory-style upper assembly for restoring an Ohlins RXF36 Evo M.2 29" fork to proper function after damage, misalignment, or wear at the upper end of the chassis. As the fork’s crown-and-stanchion structure, this is the core piece that sets alignment for smooth bushing movement and maintains front-end precision under braking and cornering. This version is the 44mm specification and is wheel-size specific for 29" applications.

• Fork-specific fit - Designed for the Ohlins RXF36 Evo M.2 29" to maintain correct chassis geometry and assembly interface
• CSU replacement - Replaces the crown/stanchion structure to address issues that can’t be solved with seals, oil, or lower-leg service alone
• 29" wheel-size specific - Matches the correct upper assembly for 29" RXF36 builds; helps avoid compatibility mistakes when sourcing chassis parts
• 44mm specification - Ensures the replacement matches the original fork configuration for consistent handling and setup
