5.0 out of 5 stars lightweight, heavy duty, October 23, 2008

takes up little space in a tool box, but makes bottom bracket overhaul a piece of cake (with BB tool, of course). Much more satisfying than bringing your bike(s) to a mechanic, and cheaper.

DIY or die!

5.0 out of 5 stars Did what it was supposed to., December 24, 2010

It did what it was supposed to do. It would have been nice to have some sort of design change made to the tool to make it less likely to slip off in either direction (while juggling the pin spanner on the other side), but it does have to be made with different bike designs in mind. It worked, not much more to say than that other than I used it on my 2008 Diamondback Lucky 24 successfully, along with a Park Tool SPA-4.

Update 09/01/2011
I used it again today on an old 1 piece crank on an late 80's Haro BMX. It worked great, the nut that held the chain wheel tight against the rest on the crank and kept the pin in the hole fit perfectly, and much easier than the newer style Diamondback I mentioned. All in all if I said it was good for unsealed American bottom brackets I might be selling some other options short, but I certainly would be dead on with three things I worked with.

Update 11/21/2011

I found this thing works well on the lock ring for a two-piece driver also. Redline Device Rear Cassette Hub 2006+ 48H 14mm Black I used the "single tooth" side on this and guessed at 30Ft lbs (I'm pretty good as a human torque wrench). Worked great.
