Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2007 GT Power Series 24 and 2009 GT Power Series 24.
- Data limitation
Only 2007 GT Power Series 24 has enough published drivetrain data for gearing calculations.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Ratio2.56:1
Estimated speed at 90 RPMGear
Uses front tire 24×1.95; rear size isn’t listed.
Gearing unavailable for this size.
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.
