Surly Disc Trucker 700c frame geometry, drawn to scale

Every tube angle and length below is from the published chart, not an illustration. The front triangle area is the number that decides which frame bags fit — and it changes a lot across sizes.

How it rides loaded

450mm chainstays, 80mm BB drop, and front/rear rack plus fork Three-Pack mounts favor stable road touring loads; the low BB is less suited to technical trail clearance.

Drawn from the published geometry and mount spec above, not from reputation.
