TheErgon GC1 Grips have been designed for bicycles that feature handlebars which have a degree of backsweep. These handlebars cause uncomfortable wrist kink which will lead to aching pains when you're riding. The GC1 grips have been designed to combat the uncomfortable wrist position by correcting the wrist angle as well as reducing pressure points and supporting the rider's palm. These grips are available in two sizes and have a combined weight of 195g so they won't add any unnecessary weight to your bike.Ergon GC1 Grips FeaturesDesigned for bikes with back-swept barsSizes: Roholff/NexusWeight: 195g (per pair)Colour: Black/Grey More info
