Surly Straggler 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.

Surly Straggler 700c — 54cm. Front triangle ≈ 1457 cm² · effective top tube 565mm · seat tube 540mm — Surly Straggler 700c in size 54cm, drawn to scale from Surly's published geometry. The shaded area is the front triangle — roughly 1457 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

Surly Straggler 700c — 56cm. Front triangle ≈ 1548 cm² · effective top tube 580mm · seat tube 560mm — Surly Straggler 700c in size 56cm, drawn to scale from Surly's published geometry. The shaded area is the front triangle — roughly 1548 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

Surly Straggler 700c — 58cm. Front triangle ≈ 1644 cm² · effective top tube 595mm · seat tube 580mm — Surly Straggler 700c in size 58cm, drawn to scale from Surly's published geometry. The shaded area is the front triangle — roughly 1644 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

Surly Straggler 700c — 60cm. Front triangle ≈ 1740 cm² · effective top tube 610mm · seat tube 600mm — Surly Straggler 700c in size 60cm, drawn to scale from Surly's published geometry. The shaded area is the front triangle — roughly 1740 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

Surly Straggler 700c — 62cm. Front triangle ≈ 1843 cm² · effective top tube 625mm · seat tube 620mm — Surly Straggler 700c in size 62cm, drawn to scale from Surly's published geometry. The shaded area is the front triangle — roughly 1843 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

How it rides loaded

425-430mm stays and 72mm BB drop are stable enough for light loads while staying road-gravel oriented; only two frame bottle mounts limit water capacity without racks or fork bags.
