The GS1 Evo revolutionizes the concept of ergonomic comfort for touring, trail, and E-Bikes by addressing issues such as aching hands and numb fingers. This makes it perfectly suitable for Brompton as well! Ergon has enhanced the popular GP1 winged grip by incorporating key features from the mountain-specific GA3. With a larger supportive wing compared to the GA3 and a more streamlined profile than the GP1, the GS1 Evo boasts a distinct textured grip zone designed for the thumb, fingers, and palm, providing an overall softer touch. Emphasizing quality materials, the GS1 Evo is crafted from a proprietary rubber compound manufactured in Germany. Whether embarking on short trips around town, participating in endurance events, or undertaking journeys across continents, the GS1 Evo has become a preferred choice for many riders!
