I recommend this product
easily fitted to a single speed used in all weathers, a nice understated look. Might prove to lack longevity, but replacing plastic fag bracket that lasted years. Feels smooth.

ProsVariety of sizes
I needed this size for my old bike and was a bit wary about the cups being plastic. I was concerned that if they jam in it would be easy to rip out the splines. It fits and works fine, I put plenty of anti-seize on the threads. When it comes to removing it I'll put the tool in the bench vice and turn the frame around the tool.

Can I use this with SJS 51948

I want to purchase a 155mm Thorn crank 9 speed. THat specifies a 110mm JIS bracket. But this one is 113mm. Will it fit please. If not do you sell the correct bracket?
Thank you for your enquiry. If you open this item on the website you will see that there is a drop down menu, from there you will be able to select the 110mm version that is available.

what length ?
07 Jun 2019
Can you advise length for use with Specialised Roubaix with Compact Double Cranks, and 10spd cassette please ?
We would not be able to advise, we do not sell Specialized and this would be a trial and error test. Specialized UK may be able to help further.

Stronglight B/B

Hi i am looking for a strong light b/b JP400 110mm with italian threads.this is to fit my strong light triple chain set.
do you any or a b/b that will fit with italian threads.

thank you

I'm afraid the only bottom bracket we have with Italian threads is a Tifosi one, but it is designed for Campagnolo ISO chainsets. The most I can suggest it using a bottom bracket designed for damaged threads as with these it does not matter what the original threading on it was.
