The Race Face Grippler grips have a clever clamping mechanism. The aluminium clamping rings do not clamp directly on the carbon handlebars and by using polyurethane instead of kraton, the Grippler Lock-On offer more comfort and durability. The aluminum clamping rings are integrated into the handle, which gives these grips a slim look and increases comfort. The Race Face Lock-On grips are available in 30 and 33 mm diameter and in different colors to match your bike's color. - Intended use: MTB - Weight: 110 g - Specifications of materials: Polyurethane - Construction: screw-on grips - Shape: sport grip - screw lock-on
