WTB Comfort Zone Clamp-On GripsThe WTB Comfort Zone grip is designed to relieve pressure build up in your palms. For those with arthritic hands or those who just never thought bike grips offered enough support, the Comfort grip is the answer. The wide rubber protrusion at the end supports the entire palm, so that you can rest comfortably on the bars. A clamp-on design also eliminates any slippage, and the 3r Triple rubber compound puts the right amount of padding where it's needed.714401750241
