The Ergon GE1 Evo Factory is the evolution of the GE1, a popular trail-oriented ergonomic grip for wide riser bars. Thanks to the feedback collected from countless Enduro World Series riders, the Ergon design team improved the GE1 by altering the compound to give a softer, more positive contact. It actively supports the correct torso/forearm position during downhill riding, offering greater control and protecting the sensitive ulnar nerve. Its forged inner clamp and fully integrated grip end connected to the inner core provides a soft, damping grip edge, comfortable right to the outer edge. These grips are compatible with carbon handlebars, so get a pair for race day and everyday.

The new GFR1 has a slim overall shape for maximum feedback, yet still provides an extremely high level of damping through the ribbed section under the palm. The lower gripping zone is aggressive to keep gripping forces at a minimum when lifting the front wheel. - Shape: Round - Lock On: Yes - Grip Shift Specific: No - Flange: No

The 710 Tour and Travel Grip features a well thought-out shape, with the wings pulled down far, making the perfect combination of comfort and driving dynamics. The 710 user is a comfort-oriented mountain biker or a sporty trekking biker. This relief wing, which is located at the very edge and deeply extends downwards, frees up space for securely grasping the grip body in all situations. The raised end of the grip externally nestles against the side of the hand, while the inside is somewhat more elevated. As a result, it specifically relieves the ulnar nerve, the median nerve, and the carpal tunnel. The clamp is located on the inner side of the grip. This increases the shock absorption and comfort on the hand’s outer side. It is not compatible with twist grips. Various rubber compounds ensure a perfect grip level and high comfort. We only use the best possible materials to avoid sticky/gummy rubber. This grip is a bit more difficult to install because the clamping is inside and only on the inner third. Use a bit of brake cleaner to slip the grip onto the handlebar very easily and it tightens up very quickly. - Weight (g) / pair: 238 - Diameter at Smallest Point (mm): 91, 101, 106 - Material: Proprietary Rubber Blend

With the 7OX grip, the sizes differ in diameter and shape. This grip is a bit more difficult to install because the clamping is inside and only on the inner third.

More support with more comfort Why not combine the best? With the GA3, the winged grip has proven its genius to the All-Mountain world. The special thing about the GP1's off-road cousin is, he locks on tight with a lightweight inner clamp. The concept combines all the relief benefits of the wing and actively supports your wrist. Your freedom of movement and the accompanying bike control remains fully intact. Riding pleasure guaranteed! What exactly are the benefits of the wings on the grips? The longer a ride is, the harder it is for a rider to maintain the ergonomically correct hand position on the bike. As a result, riders often bend their wrists too much, stressing nerves and tendons and inhibiting blood circulation. Numbness and pain in your hands are often the undesirable consequences. The GA3 grip optimizes the hand position through the Miniwings and prevents over-bending in your wrist. What is the carpal tunnel? The carpal tunnel is an anatomic passage in your wrist for nerves and tendons running from the lower arm to the hand. If the wrist is bent too much the nerves become constricted, which often leads to pain and numbness. The GA3 with Miniwing is based on the well-established and proven design of the MTB-specific GA2 grips. The particular shape of the grips provides you with great comfort and grip, without compromising the freedom of movement. This allows you to have all the control you need to tackle the most demanding of trails with full confidence. As an ergonomically perfected expansion of the GA-series by Ergon, the primary purpose GA3 grips is to provide relief out in the trail. But, they're not only perfect for the MTB category, they are also ideal on fitness-oriented and urban bikes. The ergonomic winged-grip GA3 is available in five striking colors. Ergon grips don't just feel great, they look great, too!

The 711 features perfect grip ergonomics for long-distance routes and use in racing XC style mtb. A well thought-out, highly ergonomic shape offers an especially secure grip and maximum comfort, while a full locking inner sleeve allows for infinite adjustment, allowing the rider to get that "just right" feel. The scope of delivery includes one set of grips. Strategic clamp placement increases the shock absorption and comfort on the outside of the hand. In addition, the outside surface area was increased using every trick in the book, making the new 711 Tech and Trail 2.0 as comfortable as a wing grip despite not being one. As round as necessary and as flat as possible: with the 711 grip, the outer contact surface is pressed flat, thus reducing the pressure peaks many times over. The grip security is supported by the Ergobar. This results in a flat, slightly angular grip bottom and offers a perfect form fit. This allows the grip to be guided loosely while still always keeping the bike under control. The advantages of the grip are particularly noticeable at the end of a tough marathon, but they also increase the fun on long tours or quick trips after work. Increased performance through perfect ergonomics. Various rubber compounds ensure a perfect grip level and high comfort. We only use the best possible materials. This guarantees you a long service life and no sticking of the grip rubber. The personal grip size is what matters. With the 711 grip, the sizes differ in diameter and shape.

Our initial partnership with Aaron Gwin produced numerous innovations that pushed grip technology to new levels. With the new AG2 Grips, we wanted to take things even further. We started with an ultra-soft pro compound and built it into an improved knurl pattern that provides extra tackiness and control along with reduced vibration transfer. We coupled this with our exclusive offset design that offers even more impact dampening where it is needed most, without increasing the grip diameter. We then redesigned the most impact-prone portions of the grips to provide an even better feel and accurate control when riding. - Grips feature a larger diameter than the original grips (30.5mm) with offset padding towards the rider for improved comfort - Soft Pro compound provides excellent shock absorption - Redesigned surface pattern for improved traction and vibration dampening - Redesigned ends provide an improved feel - Provide extra durability against grip blowout - Thin ribs add control without a bulky feel - Uses our race-proven Version 2.1 Lock-On system - Molded over the aluminum endcap, the end provides durability but will not gouge
