The Crombie tool is a game changer when it comes to swapping cassettes.

Whether you're a professional mechanic swapping cassettes several times a day or a DIY kind of guy this gem has a place on your tool bench. The first time a quick release spring rolls under your bench the Crombie tool paid for itself. If you like to remove the cassette for a detailed cleaning or just swapping from one cassette to another it's a big time saver and a breeze to use. This version of the tool has a Shimano/SRAM remover on one side with a Campagnolo on the other. A precision machined spline ensures maximum engagement and durability.
