Key differences

Supported differences are shown below. Data limitations are labeled separately.

  1. Gearing

    2017 Kona Hula has a 9% lower climbing ratio than 2019 Kona Hula.

    A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.

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.
