Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2011 Jamis Dakar XC Comp and 2006 Jamis Dakar XC Comp.
- Gearing
2006 Jamis Dakar XC Comp has a 6% lower climbing ratio than 2011 Jamis Dakar XC Comp.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price

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.
