depends what you need. since i just run a fixy, no brakes, all i carry is a park allen wrench set with - and + heads, a 14mil wrench for my miche hub bolts, tire levers, patch kit and emergency pump. oh and an 8mil allen wrench for my crank bolts. i can do almost anything but remove the headset and the bb with all that. then again there's not that much can go wrong on my bike
