The Race Face Grippler grips have a clever clamping mechanism. The aluminum clamping rings do not clamp directly to the carbon handlebars and by using polyurethane instead of kraton, the Grippler Lock-On provide more comfort and durability. The aluminium clamping rings are integrated into the handle, which gives these handles a slim appearance and increases comfort. The Race Face Lock-On handles are available in diameters of 30 and 33 mm and in various colours to match your bike perfectly. - Form: Sport handle - Screw lock - Application: MTB - Material: Polyurethane - Construction: Screw handles.
