Bests & Worsts Reviews from Amazon

This tool has been with me through 4000 miles of touring, plus countless commutes and day trips, boasting many successful repairs including rebuilding a front wheel. I've used it to assemble entire bikes from their shipping crates, with the addition of a 15mm wrench for the pedals. It has also been used to dis-and-reassemble furniture, and yet years later all the bits are still in perfect condition save for some light tarnish. The chain tool has worked perfectly for me from 5-8 speed chains. I've never owned 9 or greater so I can't comment on it's compatibility with those. To anyone having trouble with the flapping chain tool: unscrew the tool from it's pin and push a snug rubber o-ring past the threads. I don't know why crank bros hasn't figured this out as it cheaply solves a huge complaint. I've cast the m-19 off several times in favor of lighter, sleeker tools, but I always return to it when I decide a few dozen more grams is going to pay off when I need one of the many other tools it offers that simpler multi's lack. In my experience this is the best multi tool you can buy.
