Woodcraft 3-piece split clipon risers are specially designed to make installation and removal a snap. Our 3-piece design is race proven and makes it easy to service your clipons below the triple clamp without having to disassemble the entire front end. Special attention has also been taken to save weight wherever possible on these clamps. The bars themselves are available in both 12 and 13.5 inches lengths and are easily adjusted to whatever custom width you desire. Racers no longer have to worry about replacing an expensive complete clipon assembly after a crash because these risers use an inexpensive universal handlebar. Having an adjustable bar angle that uses a standard bar is a difference that will make your riding experience better!
