square taper for triple campagnolo crankset
13 Oct 2020
I have acquired a late 80s early 90s triple campagnolo crankset. I am looking for a sealed cartridge or cup and cone axle to fit. What can you recommend? The bb is 68mm. will the axle part have to be ISO or can a JIS type fit. Thank you.
The BB axle needs to be ISO to ensure correct and safe fitting. We only have two options - but cannot confirm whether they would be suitable - SJS Cycles part number : 30670 / 44703
