Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2012 Raleigh Rep IV and 2014 Raleigh Rep IV.
- Gearing
2012 Raleigh Rep IV has a 15% lower climbing ratio than 2014 Raleigh Rep IV.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Ratio2.33:1
Estimated speed at 90 RPMGear
Uses front tire 20×2.125; rear size isn’t listed.
Ratio2.75:1
Speed unavailable: wheel or tire size is missing or unclear.
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.
