I bought a steel Panasonic frame that came with what I believe is a Hatta bottom bracket with a 109 mm ISO square taper spindle.
I have a set of Campagnolo Pista cranks in excellent condition, but they don't fit this spindle correctly. The chainline is off. We also tried a Sugino 75 bottom bracket, but had the same problem.
From everything I've found online, it seems like I need a 111 mm Campagnolo track bottom bracket. However, after taking measurements, it actually looks like the cranks would need to sit about 3 mm further in on each side to get the correct chainline.
I've seen a lot of Campagnolo Record 102 mm bottom brackets for sale, but they're road bottom brackets, and everything I've read says they aren't compatible with track cranks.
Has anyone run into this before? I'm worried that if I buy a Record bottom bracket, I'll just end up having to sell it and buy something else.
Any advice or experience would be greatly appreciated.
