Standard stronglight bottom bracket spindle is an eye-popping 118 mm
wide, which is roughly equivalent to a Campy Triple. If you have a
post-1972 stronglight 93 crankset with a chain protector, you can just
throw away the chain protector (mail it to 4448 cather ave, san diego,
ca, 92122, for proper disposal), shift all the rings outwards, and install a
small chainring in the innermost position.

No kidding ? It looked like that to me but I thought that I must
be missing something.

The sleeved nuts are longer too. They seem to be more uncommon than long bolts,
since long bolts are common for granny gears (on other cranks) that bolt
directly to the crank.

I have an 86 BCD Sakae, and it can be run as a single, double, or triple.
Obviously the right crank will likely need to be moved outwards when going (for
example) from a double to a triple. This relocation is traditionally done by
applying a different spindle.
