Hi there, looking for some sizing info please.

Does anybody know the BB size, I think it’s 68mm shell width. What other dimensions do I need to know? Spindle length? Is there going to be an issue with chain-line?

Also what is the rear axle length spacing? Are all 9spd bikes likely to be 135mm?

the BB axle size will be based on the crank type and a shop can help with that – usually 113, 118 or 121mm for a 47,5mm chainline and it depends on crank model and from memory marins are 68mm shell – use a ruler to check tho. all 9spd bikes are 135mm, yes. hope this helps

Thanks pal, that’s fantastic. Building from bits ‘n’ bobs from the classifieds, so we’ll see what I end up with…

thanks again

A
