Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
Published weights cannot be compared because the measurement conditions are missing or differ.
Selected-size geometry
Geometry overlay
Frames share one scale and a bottom-bracket alignment. Size labels differ by brand; schematic drawing aids are identified below.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Lowest0.63:1Highest3.20:1Total range510%
Speed unavailable: wheel or tire size is missing or unclear.
Lowest0.63:1Highest3.20:1Total range510%
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.
