"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."
"While the bike is race-rigid, its IsoSpeed technology – the vibration dampening feature that holds the seat post – does a good job of keeping me comfortable over persistent surface chatter."
"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."

How tall are you?
To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.
What is your inside leg?
How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
