Hmmm, the best solution for a Stronglight triple was of course the Stronglight mod 99. which had a smaller BCD and was made primarlily, though perhaps not exclusively, to support triples. The mod 99 was made for a long time and thee are quite a few around. As far as I'm aware, no Stronglight crank had additional holes in the crankarms or the larger rings to support triples. Rather, one simply used longer chainring bolts and a set of spacers between middle and inner rings. Probably need a longer axle, too.

I'm taking that to mean the 105 wasn't modified to become a triple.
Does anyone have a Stronglight 105 triple and is it easy (no major machine work) to modify my double to take three rings?
