I bought one of these a few months back-love it,every time i need an allen key now i go to my pack to get this before my tool box..genius idea,i've used it so much more than i thought i would,saves time and effort on disc rotor changes,saddle change,headset,stem etc All my mates who have borrowed it whilst out on the trails have also loved it,pretty expensive but if its like my other topeak multi tool the alien it will stand the test of time as i've used that to death for about 6 years now and its still as good as the day i bought it.Sorry to get so excited about a tool....i'm an engineer!
