Chromag Squarewave Handlebar Grip: The Squarewave grip is designed with performance & comfort as our paramount goals. The gentle bulge fits nicely in the cup of the hand to promote long ride comfort The progressive tread is finest/softest where it meets the outer edges of the hand & coarsest under the meat of the palm for a balance of compliance & control over longer rides. The Squarewave is made with a Kraton based rubber that combines a soft 25a durometer & a proprietary additive for a combination of tackiness & durability. Chromag grips feature our unique Split-Teardrop end clamp which effectively covers the bar end while still utilizing a true pinch-clamp for the best purchase to the bar. Tear Drop Clamp
