Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2013 GT Pro Series Micro and 2001 GT Pro Series Micro.
- Gearing
2001 GT Pro Series Micro has a 20% lower climbing ratio than 2013 GT Pro Series Micro.
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.
Ratio2.92:1
Speed unavailable: wheel or tire size is missing or unclear.
Ratio2.35:1
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.
