These Fusion risers with their symmetric oval heads feature handlebar top clamps that are secured from the underside, so clean looking, as there are no bolt heads in sight. Available in 2" (5.1 cm) thru 5" (12.7 cm) in 1" increments. They take almost any of our 1" handlebars as well as our Phat, Fat Bubba and Mucho-Fatzo bars. Risers are made from solid billet aluminum, than polished to perfection and finished with top quality show chrome. Three great looking designs to choose from, Smoothie, Lone Star or Crossblade design. Riser bolts are not included but must be ordered separately. Risers are 1/2"-13 UNC threaded for our ZPN233383 riser bolts. Risers are sold in pairs.
