I have a related 93 crank/BB question. I have an early or mid 70's Motobecane Le Champion ($5 at a yard sale). It had what looks to be original Stronglight 93 crank & BB w/ 118 Stronglight axle. Right arm is fine. Left arm looked like it had been overtightened, but 2 other 93 left arms fit the same way.

Sutherland's 1985 3rd ed. lists the 118 mm for the 5 pin (ie #49) & a 120 or 123 for a 5 arm double like the 93. I need to replace the entire BB, thought I would get another Stronglight, but maybe there are other alternatives. What would be best to try a 120 or 123? What about availability? On the high end, Phil Wood lists 119 & 123 mm axles - would either of these work?

Any comments?

I will send an introduction soon.
