Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2007 Scott Speedster S40 and 2009 Scott Speedster S40.
- Gearing
2007 Scott Speedster S40 has a 20% lower climbing ratio than 2009 Scott Speedster S40.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
2007 Scott Speedster S40 had an original MSRP $301 lower than 2009 Scott Speedster S40.
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.

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.
