Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2001 GT Performer and 2003 GT Performer.
- Identity & price
2003 GT Performer had an original MSRP $120 lower than 2001 GT Performer.
Original MSRP is the published list price when new, not today’s used-bike value.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Ratio2.69:1
Estimated speed at 90 RPMGear
Uses front tire 20×1.95; rear size isn’t listed.
Ratio2.79:1
Estimated speed at 90 RPMGear
Uses front tire 20×2.1; rear size isn’t listed.
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.
