    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.
