Risk Titanium XT / SLX Brake Lever Piston RT126

The Risk Titanium XT / SLX Brake Lever Piston (RT126) is a precision replacement master-cylinder piston for select hydraulic disc brake levers. Machined from titanium alloy, it replaces the original aluminum or composite lever piston to improve corrosion resistance, dimensional stability, and long-term durability under repeated braking cycles.

This piston is designed for Shimano XT (M8000 / M785) and SLX (M7000) hydraulic brake levers that share the same internal master-cylinder architecture. It is intended for service, rebuild, or performance-focused maintenance where consistent lever feel and longevity are priorities. Seals are reused or replaced separately per manufacturer service guidelines.
