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.

Call me converted as I can confidently call the Checkpoint WSD Queen of the Quiver.

With 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.

2022 Trek Checkpoint gravel bike review: Longer, but not slacker - CyclingTips

Sep 2021 · James Huang

Major geometry changes make for a new personality that’s rowdier, but also perhaps more polarizing.

Highs
  • More forgiving handling, size-specific IsoSpeed tuning on the SLR models, reasonably headache-free cable routing, traditional frame shaping

Lows
  • Handling is more stable but also more sedate, strange bar bend on some models
