Stripping down a rusty, weathered old Raleigh Pursuit with the goal of creating a fixed gear/single speed. Needs tires and to have brakes re-routed and installed. I am wondering how big a headache I am getting myself into? I have done some reading up on the process. I am a real newbie so direction to other sites or posts is appreciated. It seems much of this will require a tech....any help appreciated!
