Risk Titanium Torx M20 Crank Cover Screw RT122

The Risk Titanium Torx M20 Crank Cover Screw (RT122) is a precision preload cap for integrated two-piece hollow cranksets. Machined from corrosion-resistant titanium alloy, it replaces standard aluminum or plastic preload caps to improve durability, corrosion resistance, and long-term serviceability.

This component is used to apply bearing preload during crank installation and adjustment. RT122 is designed specifically for crank systems that use an M20 threaded preload cap with a Torx drive interface, commonly found on Shimano-style hollow cranksets.

This is a bearing preload component only - it does not retain the crank arm under riding loads.
It is not compatible with square-taper, ISIS, Octalink, DUB, or self-extracting crank systems.
