Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Identity & price
These bicycles are categorized differently: 1996 Jamis Aurora is Mountain; 1997 Jamis Aurora is Touring.
- Handling
1996 Jamis Aurora has a 0.5° slacker head-tube angle than 1997 Jamis Aurora in the archived geometry. Frame size is not identified for 1996 Jamis Aurora and 1997 Jamis Aurora.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Gearing
1996 Jamis Aurora has a 27% lower climbing ratio than 1997 Jamis Aurora.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
1997 Jamis Aurora had an original MSRP $210 lower than 1996 Jamis Aurora.
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.
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.
