Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2010 Jamis Dakar XCR Team and 2009 Jamis Dakar XCR Team.
- Gearing
2010 Jamis Dakar XCR Team has a 9% lower climbing ratio than 2009 Jamis Dakar XCR Team.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
Gearing comparison

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.
