  2. Gearing

    2011 Jamis Dakar XCR Team has a 9% lower climbing ratio than 2009 Jamis Dakar XCR Team.

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.
