Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2004 Diamondback Coil EX and 2006 Diamondback Coil EX.
- Gearing
2004 Diamondback Coil EX has a 19% lower climbing ratio than 2006 Diamondback Coil EX.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Equipment
2004 Diamondback Coil EX has 30 mm more front travel than 2006 Diamondback Coil EX in the selected sizes.
Front travel is fork suspension stroke, not rear-wheel travel.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.

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.
