Uhm that about sums it up. I have this crankset coupled with the original cup and cone pista BB, but the chainline with a 3 mm thick 3/32" chainring comes in at 45 mm exactly. WTF? did Campagnolo change to the standard 42 mm after abandoning 151 BCD?
Using a Phil wood double fixed with Surly cog and a Sturmey Archer 1.6 mm spacer and I still need to go 1 mm outboard with the cog, but my lockring is only barely holding on with 2 or 3 threads engaged, so I'm not putting an extra spacer in there. Nothing serious, it just sucks not to have that chainline perect.
Does anyone else have experience with the 151 BCD crankset?
