Ergon GD1 Evo Factory GripsThese versatile bar grips feature more damping, control, a super-soft thumb zone as well as an inner stop design, so you can take on all the challenges that come with downhill (DH), enduro and gravity mountain bike riding. After working together with top professionals like Rémy Métailler and Vali Höll, Ergon evolved its renowned GD1 grips even further by offering greater comfort and control in demanding terrain conditions. In addition, this factory version features a unique rubber compound exclusively made in Germany for an even more precise grip feel. The GD1 Evo is twist-proof on carbon handlebars and available in two diameters.Factory Custom RubberCycling grips are repeatedly subject to mechanical wear and abrasion - particularly in an environment as tough as mountain biking. Ergon’s exclusive, Factory Custom Rubber compound maintains its high grip properties and precise structure much longer than other compounds.Conical Grip DesignThe GD1 EVO Factory has a conical, tapered shape. The grip diameter gradually increases towards the end of the grip. This increases the damping properties towards the end of the grip while the inboard diameter stays slim and responsive. The result is that you get the combined advantages of great comfort and total control on demanding trails.Features: Grip Material: Factory Custom Rubber Clamp Material: Cold Forged Aluminium, CNC-Machined Use: Mountain Bike (MTB), Downhill (DH), Enduro and Gravity Size: Slim: For S/M glove sizes (6.5 - 8.5); Regular: For L/XL glove sizes (8.5 - 10.5) Single or Pair: Pair End Plugs Included: YesTechnologies: Available in Two Sizes: The GD1 Evo is available in two diameters, standard and slim. Standard is recommended for glove sizes Large / X-Large (8.5 - 10.5) or for riders who want increased cushioning. The Slim version is suitable for glove sizes Small / Medium (6.5 - 8.5) or riders who prefer grips with a smaller grip range. Minimum Effort - Maximum Grip: The anti-slip tread pattern along with the new super soft thumb zone provides maximum grip. Additionally, the slim redesigned inner stop improves the ability to quickly position the hand and ensures full access of the shift levers. The overall design requires maximum control with less gripping force. Grip Rubber Made in Germany: The material used in Ergon grips meets the highest quality purity standards, is TÜV-certified, durable and absolutely unique in the world of cycling grips. The silicone-based, UV-resistant rubber compound of the GD1 EVO Factory is developed and manufactured exclusively for Ergon in Germany. Ergonomics, product design and engineering - all made in Germany. Internal Clamp: The internal aluminum clamp of the GD series leaves ample space for controls as well as supports a wide gripping position. The strength of this clamping system prevents any twisting of the grip, even on carbon bars. Replaceable End Plugs: The GD1’s end plugs are replaceable -a useful detail for adding even more longevity to your grips.Manufacturer’s Part Numbers: EG-42440103 Frozen Orange Regular Regular EG-42440017 Frozen Stealth Narrow Slim EG-42440105 Frozen Orange Narrow Slim EG-42440012 Frozen Stealth Regular Regular EG-42440203 Frozen Moss/Oil-Slick Regular Regular EG-42440205 Frozen Moss/Oil-Slick Narrow SlimBuy Ergon Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
