I've converted my 1970 Peugeot Px-10 to fixed gear. Everything is cool except the venerable 45 stronglight chain ring is not up to fixed gear abuse. I'd really like to put different cranks on it and run a 1/8 chain. Is there any crankset that is compatable with the stronglight bb spindle( I believe it has a Stronglight 93 spindle and crank). Thanks in advance,Frogge.
