These grips feature a clever locking mechanism-the aluminium clamps don't directly clamp onto the carbon bars-and elastomeric polyurethane is used in place of Kraton for increased comfort and durability. The aluminium clamps are concealed by the grip which gives these grips a sleek appearance and further boosts comfort. Easton Lock-On Grips are available worldwide this spring in 30 and 33mm diameters and six colours. Features Weight - 115g (30mm), 132g (33mm). Material - Aluminium clamps, Elastomeric Polyurethane grip.
