Unior Pocket Cassette Cracker (Lock Ring Tool)

This clever tool weighs next to nothing, and will allow you to remove your Shimano-type cassette on the road, if you need to do an emergency spoke replacement.

It also incorporates a spoke wrench (European size.)

I tour and have lost some spokes. Just replaced one using this tool. It takes a little while to get the tool and wheel back on the bike. But it worked like a charm. I have used a hyper cracker before and this is almost the same. Otherwise I would never have figured out how to use it. This product comes with no instructions. It really needs some.
