i gotta get a set of allen wrenches. i have a blackburn multi tool set and it you cant put any force on it. so little, in fact, that i couldn't get my set tight enough to stop from moving during a ride. defiitely should stop by home depot or the local store and grab a set. having the right tools are great, sometimes you can get by with doing it "primitive pete" style, but its often best to just use the right tool. however, i use to build computers using a leatherman, not that you need much anyways.
