All Gravel

Since its introduction in 2014, Grade has pushed the boundaries of adventure riding. The first ever purpose-built carbon gravel bike, made major waves when it was launched, winning multiple industry awards. In 2019, we pushed it even further, redesigning the frame with our floating Triple Triangle™ seatstays, and once again, the accolades poured in, being named Gravel Bike of the Year from BikeRadar and Bike Rumor. Pretty sweet laurels, right? Well we’re not resting on em! The 3rd generation gravel-pioneering Grade once again claimed BikeRadars Gravel Bike of the Year and is more capable than ever, with a new frame, featuring 30mm of “Gravel Travel”, evolved geometry, increased tire clearance, internal cable routing, and plenty of frame protection for when the road ends and the fun begins.
