Grade Carbon Pro LE

New Generation, Same Award

Our Award-Winning gravel platform does it again. In 2020 the GT Grade Carbon scored BikeRadar’s Gravel Bike of the Year. Our newest iteration in the Pro LE spec’ is back as top dog.

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.

Bike Radar Said:

"Verdict: GT's update of the legendary Grade maintains it's A+ standard."
