This is a very handy little kit, it's compact and the tools inside should have every alan key you will ever need. Not to mention some spanner pieces, and everything necessary to remove a tyre, repair a puncture and refill the tyre. This also has everything you'll need to tighten break pads and such.
The only thing that I found I needed an extra tool for was when I removed my rear wheel. I needed a separate wrench. Such a wrench could fairly easily fit into the pack and can be bought fairly cheaply, so I won't fixate on this point.
A very good product, and a good price. Recommend!
