It has, as the name suggests, 22 functions including all the Allen, Torx, screwdriver and spoke wrench keys you are likely to need when repairing a mid-ride mechanical issue. It also boasts a 12-speed compatible chain tool and an integrated tire lever. All of this is combined in a compact, alloy mini tool which can be easily stored in a saddle bag, a storage bottle, or in the pocket of your riding jersey.
