Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2007 Jamis Sputnik and 2009 Jamis Sputnik.
- Gearing
2009 Jamis Sputnik has a 10% lower climbing ratio than 2007 Jamis Sputnik.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
2007 Jamis Sputnik had an original MSRP $200 lower than 2009 Jamis Sputnik.
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.
Ratio3.20:1
Estimated speed at 90 RPMGear
Uses front tire 700C×23; rear size isn’t listed.
Ratio2.88:1
Estimated speed at 90 RPMGear
Uses front tire 700C×23; 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.
