Super heavy duty, these babies are built to last. The slimline risers are about as low as you can get, and the simple, understated design fits on just about any bike. You'll need to supply the 1/2"x13 bolts that work with your particular triple tree. Available in fully polished or black electroplate. For 1" handlebars only. These risers measure 1 3/4" from their base to the center line of your handlebar.
