Converting 21 speed to singlespeed
Hi all, new member here. i have an old 21 speed from the late 90's, was a half decent bike at the time. Now looking to give a make over and convert to singlespeed. What parts exactly would i need. I'm replacing the bottom bracket and cranks anyway so is it best to go with a singlespeed crankset and a sprocket and spacers on the back? and what chain?
