Designed for single-speed bikes or bikes with trigger shifters, our new PUBLIC Duracork grips are the perfect combination of comfort and durability. (Not compatible with twist shifters). These grips combine the classic, natural look and feel of cork with a modern material that's stronger and more durable, yet just as comfortable. Often used in fishing rod handles, Duracork doesn't crack, tear, or crumble like traditional cork. The bolt-on grip ends make installation easier than ever and eliminate grip movement. Impervious to rain and other harsh elements, these larger grips add a confidence-inspiring feel on the handlebar and greater ride comfort overall. Removes a growing point of tension.
