Bottom bracket sizing for frame swap

Jimmy125

Hi there,

I am building up a new bike and i wanna use my cranks off my old bike. The old bike had a 68-113 bottom bracket in. My new frame had a 73-122.5 bottom bracket in which needs replacing

So can a get a 73-122 again and use this with my old cranks?

Apologies for what is probably a dum question! :oops:

Many thanks

Cranks are specialized own brand 175 long
Old frame was a specialized and the new a trek
Both square taper shimano bb's.

Does that help anymore?

i would look at a 118mm axle


but it does depend on what chain line you want, presuming the same chain line.
