Questions are welcome. No pressure, no bike jargon required.
The ride, not just the specs
There is a certain kind of freedom that starts when the pavement ends. The Checkpoint was built for exactly that feeling: comfortable enough to stay out longer, capable enough to keep going, and ready to carry what matters.
We love bikes that invite you to say yes to the extra mile. This is one of them.
What makes it special
IsoSpeed comfort tech smooths potholes and fatiguing bumps in the road so you can ride stronger longer.
A new confident and comfortable Gravel Endurance geometry puts you in a more relaxed upright riding position so you can stay comfortable on even your most epic adventures.
Roll over the rough stuff with room to fit gravel tires up to 50mm wide (as measured).

“A win”
More comfortable, more approachable, and more ready for whatever type of riding you want...Has golden retriever energy, and I mean that in the best way possible.

“Fun, efficient and comfortable”
More versatile than ever but it's not afraid to go fast...Feels eager to eat up mile after mile and responds well to bursts of speed.

“Carries the torch”
Very impressed. Over the fast but lumpier sections of my loop, it did an exceptional job of taking the sting out of the vibrations...Comfort, speed and top performance but in an accessible package.
