The Ergon GMA Grips are ergonomic mountain bike grips built to improve comfort, hand position and control on the trail. Their shaped profile reduces pressure on the hands, while zoned textures provide grip and support where each part of the hand needs it. An outer stop and thumb recess also help keep your hands in a stable position on rough terrain.Key Features and Benefits:Ergonomic shape: The shaped grip supports the hand in a natural position and spreads pressure across a wider area. This helps reduce pressure points while giving you clear feedback through the handlebar.Thumb recess: A defined recess gives the thumb a clear place to sit on the grip. This reduces local pressure and helps your hand find the correct position quickly after shifting its position.Outer stop: The raised outer section helps stop the hand from moving sideways towards the end of the handlebar. This gives you a more secure hold and helps maintain bike control on rough or steep trails.Dynamic transition zones: The grip texture changes across its surface to suit different parts of the hand. More cushioning and grip towards the outside support the palm, while the inner area gives the thumb and index finger a more direct feel.Zone-specific surface textures: Different textures are used on the top and underside of the grip to improve slip resistance and damping. This provides secure contact while helping to absorb small impacts and trail vibration.Clamp positioning marks: Clear marks on the clamps help you set both grips to the same angle. This makes it easier to match the ergonomic shape to your preferred hand position and keep the setup consistent on both sides.Two grip diameters: Standard grips have a 32mm diameter, while FAT grips increase this to 34mm. The two sizes let you select a grip thickness that better suits your hand size and preferred level of cushioning.Low overall weight: The STD version weighs 110g, while the FAT version weighs 135g. This keeps the grips light while retaining the shaped profile, textured zones and support needed for demanding MTB use.Consistent hand support can make it easier to hold a stable position through long or technical rides. The GMA shape, thumb recess and outer stop work together to reduce unwanted hand movement. At the same time, the zoned surfaces balance cushioning with direct control at the thumb and index finger. This makes the grips suitable for a broad range of MTB riding styles and skill levels.The Ergon GMA Grips provide a practical option for riders who want more hand support without losing precise control of the bike. Choose between the 32mm STD and 34mm FAT versions to match your preferred grip size and complete your cockpit setup.
