Compatible with the external splined lockrings on new Shimano MTB drivetrains, featuring a 9 tooth final cog, this Crombie Tool also features an ‘S Group’ thru axle tool on the opposite side, making it perfect for use in any shop or garage that specialises in mountain and gravel bikes.

Like all tools in the Crombie family, it's there to make swapping cassettes incredibly quick and easy, with no chance of loose nuts rolling under your workbench. The 9 tooth side will work perfectly for the new 9-tooth lockring, while the other is designed for thru axle hubs.

Featuring precision machined splines for excellent engagement and made from strong, US-milled stainless steel, this tool is lightweight, reliable and easy to use.
