Hi, I'm in need of a new BB for a retro racer, I've come across a new old stock Shimano one.
The cups appear to be marked 1,37x24 but also on the box is M35x10 French 68-112
Now I know that the std british threading is the first bit (I think) the 68 is the BB sheel width & the spindle length is 112mm. However what does the M35x10 mean in relation to the fitting. I thought Shimano only produced English & italian threaded cups?
