What size BB for 68mm & Campag SR

[oldgit]

I have a 70/80s Campagnolo Super record chainset (fluted) and need to fit it to my soon to be refurbished Condor.

Any idea what size I need for a 68mm shell?

Or

Can I use a no JIS Shimano square taper. I know they're fatter than ISO. If so again what size.

112mm

As per the comment on Velobase you need to know if it's pre 1978 or not. 112mm is for pre 1978, 114.5 is needed for later cranks.

Best to stick to ISO.

I agree stick with ISO , i just got some NOS stronglight Delta cranks and the Shimano cartridge BBs with JIS axles I have do not engage very far at all into the cranks

Thank you

Mine have a 7 in a diamond, so I'm assuming 1977.

That would be 112mm then as Shawn said. It probably means you'll need the earlier type front mech as well with the thinner outer plate.

I imagine you could buy a square taper 111mm "pista " cartridge BB if you didn't wnt to fiddle around with old style loose ball BBs
