The Shimano Crank Tool (SCT for short) is specifically designed to service the lockring on Shimano single-ring cranksets for 12-speed drivetrains. It features a large hexagon that can be used with a 1.5" or 38mm spanner or locked in a vice. The clearance hole is kept to a minimum to maintain the tool engaged on the low-profile lockring, minimising the risk of damaging the tool or parts.
Compatibility:
Chainring lockrings on Shimano 12-speed mountain cranksets.
XT and Ultegra bottom bracket shells
