K, so, sort of on topic. Just want someone smart to confirm that I am actually right.
I've got a set of Campag Chorus double ring road cranks (early 90s) coming my way. I plan to (for now) run one ring fixed. I believe the chainline with a 102mm BB is 43.5 to the middle of the two rings. Assuming the back is running 41ish (Suzue Sil + EAI cog = 41.47), this means the outer ring is going to be a bit too far out for riding fixed (measured some Shimano 600s, and it's about 3.5mm from the centre to either ring, so ~47mm).
Without having the cranks with me, anyone know the actual distance to the rings? I'm guessing a 102 spindle + chain ring on the inner will be around what I want (40mm, give or take)? And I don't plan to keep the Suzue in for ever, so if I happen to come across a decent hub that's going to give me a wider chainline, I should be aiming for 47mmish (which a Goldtec + EAI would be preatty close to)?
Cheers!
