GT Grade Sport Gravel Bike
Grade has consistently pushed the boundaries of adventure riding, being the first purpose-built carbon gravel bike and earning numerous industry accolades upon its launch. The introduction of floating Triple Triangle™ seatstays in 2019 propelled it to new heights, securing distinctions like Gravel Bike of the Year from Bike Radar and Bike Rumor. Not content to rest on past achievements, the GT Grade has been further enhanced with refined geometry, expanded tire clearance, internal cable routing, and ample frame protection, making it more capable than ever for off-road adventures.
