Topstone
Carbon 4
Nothing is Impassable
Go ahead, ride it. If your idea of a fun road ride starts where the pavement ends, no other gravel bike can take you further than the Topstone Carbon and its revolutionary Kingpin suspension system. Offered with either a rigid carbon fork, or as a full dual suspension machine with the Lefty Oliver gravel fork, these bikes offer traction, comfort and control beyond the dreams of other drop-bar bikes. On everything from beat-up backroads
to full-tilt singletrack, Topstone Carbon lets you get in deep & come out smiling.
