The Cervelo Threaded Axle Fork Insert is a purpose-built adapter designed to restore threaded axle compatibility to Cervelo forks that use a smooth-bore thru-axle interface. If your fork has lost its thread insert or was supplied without one, this is the replacement that brings it back to full function — no improvisation, no workarounds. Sourced directly from Cervelo, this insert is designed to fit specific Cervelo fork models and maintain the precise fit and clamping integrity the fork was engineered for. Using the correct OEM part here matters: the axle interface is a load-bearing connection, and a proper thread engagement keeps the wheel located accurately under braking and cornering forces.
