Nut remover Shimano TL-LR11 - Y8PW04100

The TL-LR11Shimano (part no. Y8PW04100) is a specialised tool designed for fitting and removing the Center Lock locking nuts used on Shimano brake discs, particularly models such as the SM-RT10. It allows you to work neatly on the brake assembly without damaging the nut or the hub.

Made from hardened steel, it offers excellent rigidity and high durability, even when used in a workshop. Its specific internal profile ensures a precise grip on Center Lock clamping rings with internal grooves, minimising the risk of slippage during loosening.

It is used with a 24 mm spanner or a 1/2" square drive, making it compatible with standard bicycle mechanics’ tools (ratchet spanner or open-ended spanner). Compact and effective, it is particularly popular with mechanics for quick repairs on brake discs.
