Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Gearing
2000 Jamis Aragon has a 7% lower climbing ratio than 1999 Jamis Aragon.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
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.

Historical specifications are presented as an archival reference. Components may have varied by market, size, or production run. Legacy reference geometry is model-level historical data whose corresponding frame size is not identified; compare those dimensions as reference values rather than size-normalized fit data.
