Bicycling/bottom bracket removal


I been having trouble loosening my bottom bracket using my Park tool BBT-22. It ends up slipping off every time I apply pressure to turn the screw. A friend suggested putting a longer bottom bracket bolt through it so that it doesn't slip off. Ingenious I thought! Except I cannot find a blot long enough to fit through the bottom bracket tool into the BB.

Do you know where I can get a longer bolt or maybe the specifications of the bolt threading and size?  I haven't had any luck at hardware stores.
Thanks for your time!

Hi Dan,

At first I was perplexed by your question. I couldn't understand the problem until I consulted my mechanic friend.

I think the answer is simple, as he said: "Use a QR."

Well, he is a bit laconic.

But, if you run a quick release through the tool and the bottom bracket I think you will find it holds the tool snug to the races and you will be able to back them out using a properly tightened adjustable wrench.

Remember the right hand side is reverse threaded. So instead of "righty tighty" "lefty loosey" it is righty loosey. (Unless you have an old French bike, but no one has one of those any more!)

Good luck and let me know how it turns out.

I can help you with bicycle fitting problems (proper fit, numb hands, etc.), Buying help (Which type of bike, brand, so forth), basic repair problems (Flat tires, poor shifting, noises, etc.), technique questions (How to climb better, how to ride in traffic...), and even basic training questions (first race, long tour, or just a weight loss program). Some repairs are better left to the experts, we used to call this category "home repair gone bad." However, many fixes are simple and can be done by most. I will simply tell you if you should try it or take it to a shop. I will even help you ask the right questions when you walk into a shop so you can feel more confident. If I don't know an answer I can find out and get back to you.


I have worked in bicycle shops or the bicycle industry since 1984. I started racing around that time but rode bicycles and did some touring before that. I have managed large shops in the upper Midwest, been invited to join a professional team as mechanic, which I turned down so I could open my own shop. I have built wheels for two US National Champions. I have also been a consultant to retailers and manager of a bicycle fitting system company here in the US. My greatest joy is helping people get into riding and be more confident about their riding and bicycle.

Doesn't really apply but I do have a BA in English/History (Both very marketable - that is why I stayed in bicycles!) And had been working on my Master in Education before I thought better of that.
