The ROCKSHOX Race Day lockout repair piston was developed by Andreani technicians to solve a reliability issue with the 32mm and 35mm RockShox SID Race Day cartridge, which has a component inside that tends to deteriorate after a few hours of use, causing it to stop locking.
The modification involves replacing the lockout valve piston with an identical one but with a different seal, which is replaceable, allowing for simple maintenance rather than complete piston replacement.
This kit can be installed at one of our authorized centers and requires the use of a specially developed key with code 14.F14.003.
