Hi everyone, I started working on converting a Dahon Espresso (Pininfarina) to a road bike. I bought a second-hand Shimano FC-4550 (Sora/Tiagra around 2011) 175mm crankset and a Shimano Tiagra BB-RS501 68mm bottom bracket. The problem is that the right crank is max 1mm away from the frame and the left crank is already touching the frame. Can anyone give me some advice and experience with this? I'm not very familiar with Hollowtech bottom brackets, I don't know if there are any spacers that can be put in without negatively affecting the attachment of the left crank? The chainring is also close to the frame, but unlike the cranks, it's not completely touchable.

I´ve tried to write to Schocca about his excel parts list that he posted here for his fantastic road conversion, but unfortunately he doesn't come here anymore. Does anyone have that list from him to shere? I know that he probably had a very similar crank there, but I don't know why it doesn't work for me.

Thanks a lot.
