Gravel Travel

The Grade frame’s Triple Triangle design with floating stays offer as much as 30mm of “Gravel Travel” without rubber bumpers, pivots or mechanical features. This was achieved in part by our Dual Fiber Dynamics (DFD) located in the floating stays - a combination of low modulus, solid core, long strand glass fibers molded to an optimum shape and then wrapped in carbon for added strength and smooth transitions.

Suspension fork compatible

If the rough and chunky are your preference and you need more than Grade’s 30mm of Gravel Travel offers, add a suspension fork for even more rowdiness!

Integrated Frame Protection

Grade is just as comfortable on rough single track than it is on smooth tarmac. So, we’ve added robust frame protection on the downtube for the inevitable rock strikes and on the chainstay to safeguard against chain slap.

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.
