Going to build up a cx frame with 68mm bb and 135mm spacing. Fitting an slx mtb cassette with a sora double road crank 34/46 . Im unsure wether to use a road or mtb bb. Im thinking it could be an mtb with a spacer on the drive side due to mtb rear end spacing
But im open to the input of people who actually know what they are doing 🙂
Cheers

Use a road bb. An mtb bb with a spacer will be the same (road cups are wider).
