NOTE: Longer cables may be required when installing handlebar risers. Allow you to adjust your handlebar height easily on the trail, or in the back country, to increase your comfort by customizing your sled and its feel to you. Allow you to clamp a stock 7/8" diameter handlebar, or you can remove the 7/8" reducers and then clamp a 1 1/8" oversize aluminum bar - reducers lock into risers to ensure no slippage between components and serrated teeth ensure maximum gripping power on the handlebar. Risers take the guess work out of deciding which size to buy, with a choice of 4" to 6" rise, or 6" to 8" rise. Independent left and right risers adapt to any "T-stem" width, making them very universal and usable on different makes and models. Included wrenchless lever, allowing risers to be adjusted without the use of wrenches or other tools. Give you the option of fitting one sled to multiple riders in minutes. Designed to replace OEM pivoting riser blocks. CNC-machined from billet 6061-T6 anodized aluminum Made in the U.S.A.
