The Slater Jr Lock-On features a tapered core that is slotted to keep the grip secured to the handlebar. It utilizes our proven one-piece integrated collar and core design. With a slimmed-down profile (diameter and length), it ensures an optimal fit for the growing rider. With a small diameter, the grip only fits 19mm bar ends (not 22.2) to ensure we can still utilize an SDG icon pattern to maximize comfort and overall handlebar control, resulting in a positive riding experience.
