Can anyone remember the spacing between the inner and outer chainlines on a Shimano 600 crankset? I do not have any with both rings still on to measure.

Scroll down to the Shimano crank info...then scroll almost all the way to the bottom and look in the table...looks like it's 5mm between rings with inner at 41mm, outer at 46mm, and the midpoint at 43.5mm. Hope that helps.

Thanks. I knew I had seen it there somewhere, His website has become like an encyclopedia. Even google indexing is not enough anymore. We have to put our collective brains together to produce something more powerful.
