“Ridiculously light and fast”
Gravel bikes have come a long way in a short time, and the Checkmate may demonstrate that better than any bike...Could easily see this bike being my one-bike option.

“Speed on all kinds of surfaces.”
While the bike is race-rigid, its IsoSpeed technology—the vibration dampening feature that holds the seatpost—does a good job of keeping me comfortable over persistent surface chatter.

“Surprisingly fast and agile”
Racy-feeling, yet I’ve found it easy and fun to ride...As stiff and reactive as anyone is ever likely to need, yet it's highly controllable and confidence-inspiring.
