Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2008 Jamis Dakar XAM 2.0 and 2007 Jamis Dakar XAM 2.0.
- Gearing
2007 Jamis Dakar XAM 2.0 has a 8% lower climbing ratio than 2008 Jamis Dakar XAM 2.0.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Equipment
2008 Jamis Dakar XAM 2.0 has 20 mm more front travel than 2007 Jamis Dakar XAM 2.0 in the selected sizes.
Front travel is fork suspension stroke, not rear-wheel travel.
- Identity & price
2007 Jamis Dakar XAM 2.0 had an original MSRP $525 lower than 2008 Jamis Dakar XAM 2.0.
Original MSRP is the published list price when new, not today’s used-bike value.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.

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.
