A great value bundle, the Revolution Tune Up Tool Kit provides the basics for simple servicing in a versatile case.
With three Y-wrenches, a chain tool, twin compartments for screws and the like in a book-style case that you can screw to the wall, Edinburgh's Revolution is a useful kit for under £40.
The kit also includes a 14mm socket for removing chainsets from older style bikes, and even a 'mushroom' adaptor for removing cranks from Shimano Octalink 1 cranks.
Tool quality is bearable rather than great, and we’d rather have an external bottom bracket tool than very rarely used cone spanners. A freehub lockring and big 8mm Allen wrenches are bonuses.
The grip on the interchangeable-bit screwdriver is a little small but adequate for gear adjustments, but the Y Allen key is too long to secure brake bolts, the spoke key slips on stubborn nipples, and the cone spanners aren't hardened so the edges round off with hard use.
Despite these niggles, it's a great value bundle – it would cost you a lot more to buy these tools individually.
