Ergon GT1 Grips Four Positions, Zero Numbness Long days on a flat-bar bike have a way of finding every pressure point on your hands and wrists. The GT1 was designed around that specific problem. Instead of locking you into one grip position, the ergonomic wing shape, upturned outer end, thumb rest, and palm zone give you four distinct places to shift your hands as fatigue builds. You can move between positions without stopping, which means your muscles get rotation and rest instead of accumulating hours of the same load. An integrated clamp keeps the profile smooth with no exposed edges, and the clamp opening sits on the underside so nothing bites into your palm. For commuters, tourers, gravel explorers, and e-bike riders who clock real mileage, this is the grip that makes long rides feel shorter. Features Four ergonomic hand positions standard grip, outside grip, thumb-up, and palm position let you actively vary hand and arm position to shed upper body tension over long rides Extra-large ergonomic wing spreads pressure across the palm and supports the wrist in a natural, neutral position to reduce fatigue and numbness Upturned outer grip end acts like a short bar end, increasing contact surface and relieving wrist and arm strain in the outside grip position Integrated lock-on clamp with forged aluminum construction clamp opening sits on the underside for a smooth, edge-free grip surface and a secure hold without shifting Two ergonomic sizes, Small (140mm) and Large (148mm) differ in grip thickness to match hand size; both share the same wing size and length Not compatible with twist shifters fits standard flat-bar setups; intended for touring, commuting, gravel, hybrid, e-bike, and cargo use Specifications Grip Type Lock-on, Ergonomic Wing Outer Diameter Length140mm (Small) / 148mm (Large)Clamp Style Integrated single lock-on, forged aluminum, underside bolt access Core Diameter22. 2mm Compound / Durometer Weight Intended Use Commuting, Gravel, E-Bike | Ergon | Gt1 Grips | Black | Large
