I recently acquired an 85 Trek 620 from a yard sale for $15! (pairs nicely with my 85 600)

Its in decent shape and I look forward to upgrading a few bits to make it a reliable commuter/ occasional tourer.


The main issue is that I cannot shift into the largest chainring no matter what (FD is original Huret and not hitting its limit and height is correct).

It's a chainline issue that I'm narrowing the culprit down to the drive side crank arm or spindle as only the drive side crank arm was swapped out to Sugino, where left side is still Shimano for some reason.

Maybe the spindle too was switched out for something too long when the crank arm was swapped I dunno.


Long story short, I came to ask a question which is: Does anyone out there know or have access to measure and tell me the stock spindle length on a Trek 620???? I would be forever grateful!
