These simple yet functional handlebar risers are the perfect thing for those on a budget. They are near indestructable and will mount on your existing 7/8" handlebar mounts. These will raise the height of your bars 2 inches. Longer bolts will be needed (not included) to mount these to your bike. As so many bikes existing mounts are different thicknesses, bolts are not included. We recommend going to your local parts store for the correct length for your bike.
