Well, I would need to re-assemble it to get that measurement---not sure. I do recall that a portion of the spindle was exposed in the old set-up. When I got the bike, it was road-worthy, but suffered from occassional "chain-suck" between the first and second rings on the original SR triple crank----which is one of the reasons I'm getting a new crank. Maybe the suck was caused in part by a poor chain-line??? The old BB simply needed to be repalced, so here I am...
