Key differences

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

  1. Frame geometry

    2026 Kona Process X has 17 mm more stack than 2021 Kona Process X in the selected sizes.

    More stack places the frame reference higher, not necessarily the handlebar.

  2. Gearing

    2021 Kona Process X has a 54% lower climbing ratio than 2026 Kona Process X.

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

  3. Equipment

    2026 Kona Process X has 20 mm more front travel than 2021 Kona Process X in the selected sizes.

    Front travel is fork suspension stroke, not rear-wheel travel.

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.

Rear tire: 29×2.4.

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.
