Chain line for Raleigh

forty45

Devout Dirtbag
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).
 
Narrower bottom bracket by the same amount as the chainline is off.

But I think you want us to tell you to not be bothered?
 
No, I want to get this right (and not buy too many more cartridges in the process!).

Would getting a 107mm one be the way forward, losing 3mm each side? Now ordered - fingers crossed!

I see there is a JIS taper and a JIS low profile one - how do you know which type your crankset needs??
