I am converting one of my old road bikes into a fixed gear but i don't know how to deal with the crank/chainrings. Should i just replace the whole setup? Also i am having trouble with the brakes, i replaced the original 27 1" x 1/4" wheels with just 27" ones so i am having trouble finding calipers with long enough arms to reach the smaller wheels. Any advice would be great as this is my first conversion project.
thanks
