ParkTool BBT-4 Tretlagerwerkzeug

Looks like a solid professional tool.

It does what it's supposed to. Good product.

Easy to use got old one off with no problems.

The tool was ok but the bottom bracket was seized and the tool didn't allow enough purchase. If you have a seized bracket you need the socket type tool

This is a quality bit of kit, and good value for money considering how often you're likely to use it. It is a bit tricky keeping it aligned properly but that's more to do with the design of the BB rather than the tool

An economic and effective tool for Campagnolo bearing cup removal. Centaur tapered square axle.

Usual park tool quality. If used correctly it should stand up to a lifetime of use.

I really needed to adjust my bottom bracket as it has be come somewhat uncomfortable of late.I completely misunderstood the description and now, having got back from A&E I is apparently for your bicycle and not your bottom.Don’t make my mistake, the nurses were giggling.
