Park ToolBBT-69.4 Bottom Bracket Tool(Return to Product Page)

I bought this to install disc brake rotor lockrings. It fits over the protruding end of the axel and seems much easier to use with less chance of slipping than a thin flat lock ring remover. I use it with a large Park Tool beam torque wrench . Nicely machined and finished.

I bought this to install my Campagnolo centerlock disc brakes lock rings. Although the tool fit the outside tooth pattern, the inner diameter of the lock ring did not fit my hubs. Thought about returning the tool, and BikeTiresDirect was ultra helpful providing a return authorization and return label. However, the tool fits my Campagnolo bottom bracket cups. So I decided to keep it!

And that blue Park Tool color? freakin' awesome!

The bike shop I use did not have this. YOU ARE DEAD IN THE WATER WITHOUT IT. With it, a few seconds is all it takes. Get what you need to work on the bottom bracket!

Started using disc brakes, thought I had the right tool for mounting the rotors. Did some research. This is it.
