GT Grade Carbon Pro LE Gravel Bike
Since its inception, Grade has continually pushed the boundaries of adventure riding. As the first purpose-built carbon gravel bike, it left a lasting impact, receiving numerous industry accolades upon its debut. In 2019, the introduction of our floating Triple Triangle™ seatstays propelled the bike to new heights, earning prestigious titles such as Gravel Bike of the Year from Bike Radar and Bike Rumor. Never content to settle, Grade has undergone further enhancements. The latest iteration features refined geometry, expanded tire clearance, internal cable routing, and enhanced frame protection, making it more capable than ever for off-road adventures.
