Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Identity & price
These bicycles are categorized differently: 2021 Kona Sutra is Touring; 2025 Kona Sutra is Gravel & Cyclocross.
- Frame geometry
2025 Kona Sutra has 12 mm more stack than 2021 Kona Sutra in the selected sizes.
More stack places the frame reference higher, not necessarily the handlebar.
- Handling
2025 Kona Sutra has a 0.5° slacker head-tube angle than 2021 Kona Sutra in the selected sizes.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Gearing
2021 Kona Sutra has a 9% lower climbing ratio than 2025 Kona Sutra.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
2025 Kona Sutra had an original MSRP $100 lower than 2021 Kona Sutra.
Original MSRP is the published list price when new, not today’s used-bike value.
Selected-size geometry
Geometry overlay
Frames share one scale and a bottom-bracket alignment. Size labels differ by brand; schematic drawing aids are identified below.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.

How it works
Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.
Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
