The new Checkpoint is not just better than the previous generation, it’s one of the best gravel bikes I’ve been on.Bicycling
IsoSpeed undoubtedly works. The back end of the Checkpoint was as comfortable as any that I’ve experienced on a performance oriented bike.BIKEPACKING.com
Call me converted as I can confidently call the Checkpoint WSD Queen of the Quiver.
BikerumorWith a frameset built to take a pounding, heaps of tyre clearance and mounts for almost anything, the Checkpoint is well-featured; when appropriately configured, it should be versatile enough to take you almost anywhere.

Mounting points for every bag you can think of
Non-proprietary seat-post provides options
Internal storage is convenient
Downtube protection eases worry
Threaded bottom bracket
Ideal all-around gearing
Short stem for added stability means handlebar/knee interference

Major geometry changes make for a new personality that’s rowdier, but also perhaps more polarizing.
More forgiving handling, size-specific IsoSpeed tuning on the SLR models, reasonably headache-free cable routing, traditional frame shaping
Handling is more stable but also more sedate, strange bar bend on some models
