    No geometry is recorded for 2010 Kona Fire Mountain and 2011 Kona FIRE MOUNTAIN.

  2. Gearing

    2011 Kona FIRE MOUNTAIN has a 8% lower climbing ratio than 2010 Kona Fire Mountain.

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.
