Brakco Centrelock Lockring – Oversized

The Brakco Centrelock Lockring is designed for Shimano’s centrelock rotors, including hubs with 15 mm and 20 mm through-axles.

The lockring has an approximately 4 mm thick spline pattern for excellent tool engagement, to reduce the chance of tool slipping or wear on the lockring. This lockring requires a compatible Shimano hollowtech II bottom bracket tool for installation and removal.

Please note that the lockring is not designed for disc rotors larger than 210 mm.
