This is a handy tool for undoing quick-connector links if you want to remove your chain for cleaninglube and reuse. It also does double duty with two very sturdy tire levers, the plastic is a lot denser than you'll find on cheaper levers.
Little on the thicker then I expected.
Takes up space in the saddlebag. But it double as the tire leavers so, it makes up for it. Havent had chance to use it on the road yet.
Have used KMC, SRAM and shimano dura ace chains, MTB and Road, works excatly like it says, makes popping a quick-link off and on simple and fast. After I wore out a KMC chain way too quickly (less than 1,000 miles...), went back to shimnano dura-ace and it works great on these too. Very hard plastic or nylon (ABS?) with what feels like a steel core, won't bend or break! Works great as tire levers too! Very happy with this, saw a friend use their's and knew I had to get one. BTW, only place I could find this was here at WB.
