Fixing a chain on the roadside or trailside when you're sweaty, muddy, or freezing is pure joy, right? Wrong. A huge part of the agony is trying to line up and leverage the pocket chain tool with just 2 hands. The Park Tool Folding Chain Tool is no bigger than regular chain tools, but takes the frustration level down--it folds out creating a work platform with the right kind of leverage you need to make the job easier. It weighs about the same as a regular chain tool too (125g), so all you really stand to lose is a chance to be really frustrated.
Light and compact at 125g and 2.8in x 0.8in x 0.85in
