Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2004 Kona Unit and 2003 Kona Unit.
- Gearing
2003 Kona Unit has a 6% lower climbing ratio than 2004 Kona Unit.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Ratio2.00:1
Estimated speed at 90 RPMGear
Uses front tire 26×1.9; rear size isn’t listed.
Ratio1.88:1
Estimated speed at 90 RPMGear
Uses front tire 26×1.9; rear size isn’t listed.
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.
