Many riders prefer grip shift because they find it easier to shift. So they shift more often and therefore are always in the perfect gear. Like XX1, XO1 features Rolling Thunder ball bearing technology. Rolling thunder is a system of three rows of a total or 120 bearing that virtually eliminate friction and play for less shifting force and a quality, smooth feel.
Speed Metal refers to full metal indexing for reliable, crisp shifts. These systems work hand in hand to deliver long-term performance under all weather conditions. Other features include a barrel adjuster to fine tune cable tension on the fly and an aluminum cover (XX1's cover is carbon fiber). Both the left and right grips are locking to your grips won't twist or come out of position.
Includes shifter, both left and right locking grips and derailleur cable.Features
