crank to chainstay clearance?

bikenut2010 · May 30, 2013

just wondering what the tolerances should be regarding equal clearance from crankarm to chain stays... I have an older bike with a cottered crankset and the non drive side is around 3 mm from arm to chain stay but more like 10 mm on the drive side... :roll:

Blimey, for some old cottered chainsets you had to take a taxi to get from the crank to the chainstay.........what's the chainline like?

Remember sometimes you had to have a lot of room for a chainguard and, god forbid, a chainbath.

Are you thinking that the 3mm is a bit narrow? Replacing the spindle should be easy, once you find the right spindle. On the other hand old solid steel cranks should have very little flex.

you mean the measurements?

44 mm from centre of seat tube to middle of point between chainrings, rear as per http://sheldonbrown.com/chainline.html

is that the right way?
