- Data limitation
Only 2009 GT Compe has enough published drivetrain data for gearing calculations.
- Identity & price
2008 GT Compe had an original MSRP $120 lower than 2009 GT Compe.

Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.

Gearing unavailable for this size.
Ratio2.54:1
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.
