BBB Toolbox Compact BTL59 review£99.00

Shimano transmission tools

BikeRadar score3/5

This 11-piece kit covers most jobs associated with a bike’s brakes and transmission but omits a tool for removing the plastic retaining nut on the left-hand crank. 

Otherwise, the cassette removal tool has a handy locating dowel that helps prevent slipping, and the tool for holding the chainring nut works well, as do the spoke key and chain wear gauges. 

The Y-shaped Allen key is useful, but the handle fouled the seat tube when we tried to fix a rear brake centre bolt on a bike with chunky chainstays. 

The chain splitter is of inferior quality to the rest of the tools in the kit. A version is also available for Campagnolo aficionados.
