Renthal Tapered Dual Series Grips Renthal tapered dual series grips have all of the benefits of the Renthal classic dual series grips， but feature an oversized thumb diameter， which tapers down to regular size at the ends to match the contours of a closed fist for maximum comfort and control. They have increased material in the sensitive thumb area that offers more cushioning and damping against vibration without reducing control. The grips use a soft compound for the outer diameter which is in direct contact with the palm， fingers， and thumb， and a firm compound is used for the flange， inner sleeve， and outer end for maximum durability.
