Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2005 Jamis Durango Sport SX.
- Gearing
2005 Jamis Durango Sport SX has a 6% lower climbing ratio than 2002 Jamis Durango Sport SX.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
2002 Jamis Durango Sport SX had an original MSRP $100 lower than 2005 Jamis Durango Sport SX.
Original MSRP is the published list price when new, not today’s used-bike value.
Gearing comparison

How it works

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.
