Kona Sutra 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.

Kona Sutra — 48. Front triangle ≈ 1212 cm² · effective top tube 523mm · seat tube 480mm — Kona Sutra in size 48, drawn to scale from Kona's published geometry. The shaded area is the front triangle — roughly 1212 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

Kona Sutra — 50. Front triangle ≈ 1296 cm² · effective top tube 538mm · seat tube 500mm — Kona Sutra in size 50, drawn to scale from Kona's published geometry. The shaded area is the front triangle — roughly 1296 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

Kona Sutra — 52. Front triangle ≈ 1386 cm² · effective top tube 555mm · seat tube 520mm — Kona Sutra in size 52, drawn to scale from Kona's published geometry. The shaded area is the front triangle — roughly 1386 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

Kona Sutra — 54. Front triangle ≈ 1477 cm² · effective top tube 571mm · seat tube 540mm — Kona Sutra in size 54, drawn to scale from Kona's published geometry. The shaded area is the front triangle — roughly 1477 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

Kona Sutra — 56. Front triangle ≈ 1575 cm² · effective top tube 588mm · seat tube 560mm — Kona Sutra in size 56, drawn to scale from Kona's published geometry. The shaded area is the front triangle — roughly 1575 cm² of space for a frame bag. Wheels are indicative; frame lines are accurate.

How it rides loaded

445mm chainstays and 70-74mm BB drop are load-stable geometry; missing verified mount data prevents a complete cargo assessment.

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

What it can carry

Mount provision and clearance, as Kona publishes it.
