Abbey Bike Tools Crombie Cassette Lockring Tool

The Crombie is intelligently designed to take up as little space as possible, whether in a travel toolbox or personal workshop. The handled versions of the Crombie are designed to fit inside Abbey's Whip-It chain whip tool, saving even more valuable tool box space. The expert design and thin inner profile of the Crombie allow you to remove cassette lockrings and swap cassettes without needing to remove the quick release from the axle. 

Dual-Sided Standard & Super Light 

The standard tool has a dual-sided head that is compatible with both Shimano / SRAM and Campagnolo lockring splines.

The SL version features a hollowed out handle and is compatible with both Shimano / SRAM and Campagnolo lockring splines. It is an excellent option for travelling mechanics or those wishing to reduce the overall weight of their toolbox.

Dual-Sided Thru Axle & Super Light

With its adoption of thru axle standards, the bicycle industry has fortunately settled on a standard of 12mm for the rear thru axle. One side of the Crombie Thru Axle tool is fitted with a 12mm pilot pin to help keep the tool properly aligned during use. The other side is designed for standard quick release hubs.

The SL version features a hollowed out handle.

Both versions of the T/A Crombie are compatible with Shimano / SRAM cassette lockring splines, as well as centerlock brake rotor lockring splines, but not compatible with Campagnolo wheels.

3/8" Socket

This ultra-compact version of the Crombie is designed for 3/8" ratchet handles and torque wrenches. It shares the same deep socket and thin walls of the original Crombie, and is compatible only with Shimano / SRAM lockring splines.
