Hi all. I'm in the process of rebuilding a presumably '50s CILO for my nephew. It had a stuck Stronglight French threaded [not Swiss, which surprised me] 8 sided fixed cup. Previously i'd filed a 37mm Park fixed cup tool to about 38mm to fit Stronglight cups but that tool was loose on this cup which measured about 37.2mm. So i filed a standard Park 36mm tool to just fit this cup. Held tight against the cup w/ a bolt [inserted from the bb shell], a large washer and nut, and given a sharp counterclockwise rap w/ a hammer it came loose rather easily. I'm offering this up as i've never seen Stronglight specific cup tools. Cheers, Billy Ketchum; Chicago, IL; USA.
