Hi

Thank you for your enquiry, unfortunately 121mm is the shortest axle length that we have available in the 70mm bottom bracket shell version.

French Bottom Bracket..

I have a frame with french threads and the current bb is a cheap bsa with 2 non-drive side cups, should I buy a french one or is it possible to use this bb?

Note: the threads are still present but I think they might be a tad damaged.
Hi there,

I would have your local bike shop to check the threads and go from there, if they are damaged you could fit a threadless bb, but ideally one suited to thread in correctly.

Thanks

Can This Replace The Bottom Bracket In My Frame
By
29 Mar 2016
I have a alu frame with damaged threads. The old bottom bracket is a BB UN52 70 mm (36x24T). Can this replace the broken bottom bracket, and wich size should I choose if so?

Thanks.
Hi,

As your previous bottom bracket is 70mm then this is the correct replacement to go for. You will need to measure the overall length of your current bottom bracket as you will need to match that to one of the options from the drop down menu.

Thanks.
