Details

The GR:1 has been built to travel off the beaten path. We start with our new sealed bearing 650b wheel set, equipped with the light and supple Teravail Rampart 47mm wide gum wall tires, designed for rough pavement, gravel roads and well beyond. We switch to a lower range 34t front chainring as part of our preferred 1x10 drivetrain for greater climbing ability when the road gets rough and goes upwards. Upgraded SRAM level hydraulic brakes provide consistent, confidence inspiring stopping power, without fading over long descents. We love the feel of the premium Brooks Cambium C17 saddle and Cambium grips, that give all weather control and comfort you can settle into for long days exploring in the saddle.
