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.
SJS Customer Service:
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.
