Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2003 GT Power Series Micro and 2006 GT Power Series Micro.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Ratio2.50:1
Speed unavailable: wheel or tire size is missing or unclear.
Ratio2.40:1
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.
