Can I ask for help on the chain line for a late 1980's Raleigh road frame.
I have fitted a Shimano 600 double chainset and accoring to Velobase the chainline should be 43.5mm and the bottom bracket 113mm. I have a UN53 113 bottom bracket and when installed the measured chainline looks like 47.5mm, which is what an MTB should have.
All advice would be welcome. I then have to sort the rear wheel spcing (126 OLB which I have put a 7 sp HG cassette on to replace the original 6 speed one).
