I've already pulled these cranks off a peugeot le vagabond from either 1984 or 85. I believe i used 22mm threaded puller and it seemed to work okay. know i'm reading that some of the older stronglight cranks used 23.35 mm pullers, and that you can mess up your cranks when not using the correct puller. i would like to know which size is correct for these cranks. did these cranks use iso or jis tapers for the bb, when i inspected them they appeared to be iso, but i have little experience with this and want to be sure. i would like to replace it with a sealed version. the bb measures according to sheldon brown site method d=129 overall length, c=39,b=55,a=35. the cups to the bb thread on british standard because i believe the bike is japanese. any ideas on where to find a sealed bb that comes close to these specs. this french stuff will drive you mad!
