Does the bottom bracket on Surly Pugsley need to be replaced with a like for like surly part (100mm external bottom bracket) or will any 100mm external bottom bracket be compatible..?
The surly part is quite expensive compared to some other brands, but I can't be certain that they are compatible with the Surly O.D. crank.
First time doing this job, apologise for any ignorance.
Appreciate any insight.
