I have a Swobo Accomplice and it's all original. Today I decided, finally, to try out the fixed cog. The chain won't fit it, it's too small to get in between the teeth, just like the one in the picture below. I think it's pretty messed up that they spec'd the bike like that. My question is this: Since I don't know what size chain I currently have (I have limited SS education), does anyone know what size it needs? I am planning on getting a WI freewheel and it requires a 3/32. Hopefully that is the size the fixed cog needs?
