- Equipment
2012 Kona Big Unit has 20 mm more front travel than 2009 Kona Big Unit in the selected sizes.

Estimated speed at 90 RPMGear
Uses front tire 29×2.1; rear size isn’t listed.
Gearing unavailable for this size.
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.
