Hollowtech II Crank Bolt Tool

There's only so much to say about this tool and what it does. Instead, we can talk about how often (if you're at all like me) you've been face to face with a Shimano crankset and unable to find one of the twenty of these you've already got. That alone should make you want to get at least a couple more. The price doesn't hurt either

The tool features an 8mm hex in the middle of it for those really stuck caps.
