The GCS Grips wrap a soft 20A rubber compound around a tapered recycled composite core, giving hands a secure hold without going stiff or numb on long descents. A knurled top surface supports the palm, while raised blades under the fingers add a locked-in feel through rough sections. A slim aluminum clamp locks the grip to the bar without adding bulk, and the rubber itself is made from recycled material, so the GCS Grips pair comfort with a lighter footprint. Two sizes, Thin and Thick, let riders match grip diameter to hand size. What Our Gearhead(R) Experts Are Saying:"My hands were soaked halfway down a wet descent, and the rubber never went slick on me."
