Brooks MT21 Toolkit

The Brooks MT21 Toolkit is a 21-piece cycling multi-tool with the kind of finish you would expect from Brooks. It covers the common bike adjustments you are likely to need on the road, at home, or while travelling, and comes complete with a leather sleeve.

It is especially useful for touring riders, commuters, Brooks saddle owners and anyone who wants one tidy tool to keep in a pannier, saddle bag, desk drawer or workshop shelf.

Why we like it

The MT21 covers a useful mix of modern bike adjustments. The hex keys handle most common bolts, the Torx keys suit many disc brake and component fittings, and the chain tool is handy for longer rides where a broken chain would otherwise end the day.

The Brooks saddle spanner is the detail that makes it especially useful for Brooks owners. If you ride a leather Brooks saddle, this gives you the correct tool for saddle tension adjustments alongside the usual ride and workshop essentials.

Best for

Choose this if you want a well-equipped multi-tool for commuting, touring, bikepacking, travel or home adjustments. It is a good fit for riders who carry tools in a bag or pannier rather than trying to keep everything as small and light as possible.

It also makes sense as a gift for someone with a Brooks saddle or a classic bike build, because it feels more considered than a plain workshop multi-tool.

Good to know

This is a more substantial multi-tool, not the smallest option for a jersey pocket or minimalist race kit. If you are trying to save every gram, choose a smaller tool with fewer functions.

The MT21 is best carried in a pannier, handlebar bag, saddle bag, frame bag, tool roll or kept at home for quick adjustments.

As with any multi-tool, it is made for adjustments and roadside fixes. For stuck bolts, major servicing or high-torque workshop jobs, a full-size workshop tool is still the better choice.
