crankbrothers 10 Function Multi Tool

This 10-piece tool has an aluminium body for low weight. Opening the Allen keys takes a little bit more oomph than usual, but this gives greater stability when you're spinning bolts into threads and particularly when you're using the Phillips and flat bladed screwdriver.

The Allen keys are longer than most, and so the smaller sizes tend to twist as you increase force on the handle, but it's okay with the 4mm and larger Allen key and the extra length of the 8mm Allen key makes it a bit easier to spin a pedal into the thread of a crank arm.

There's no spoke key included on this one, but the lifetime warranty on all Crank Bros multi-tools is a bonus.

The Allen key sizes are 2, 2.5, 3, 4, 5, 6 and 8mm and there's the obligatory T25 Torx driver too.

Superior stability when using a screwdriver and a good price

This one's a real belter. While it isn't that compact, you can get sufficient leverage in most situations. Make room for this in your pack next to a quality compact chain tool, such as a Park Chain Brute, and you'll have little to fear when the mechanical gremlins attack mid-ride. There's no spoke key, but if you know how to use one you'll have one already.

Construction is great and it has a lifetime warranty.
