I'm converting a pretty rusty old Fuji Absolute into a fixed gear and I wanted to swap the crank or at least get rid of the larger chainring. I managed to pop off both dust caps and remove the nut on each crank arm with a socket wrench but then I had a lot of trouble removing the crankarms from the BB. I managed to get the left one off after riding around nutless for a while; however, I can't seem to remove the right crank arm no matter how hard I try. Would it be worth getting a crank puller to remove the right side and finally take apart the chainrings? Or is there another method I can use to get it off easily? Thanks!
