Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2012 Marin Cortina and 2009 Marin Cortina.
- Gearing
2009 Marin Cortina has a 6% lower climbing ratio than 2012 Marin Cortina.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
2012 Marin Cortina had an original MSRP $400 lower than 2009 Marin Cortina.
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 = pedal turns per minute.
Speed unavailable: wheel or tire size is missing or unclear.
Uses front tire 700C×34; rear size isn’t listed.
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.
