Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2009 GT Avalanche Expert and 2011 GT Avalanche Expert.
- Data limitation
Only 2011 GT Avalanche Expert has enough published drivetrain data for gearing calculations.
- Equipment
2011 GT Avalanche Expert has 5 mm more front travel than 2009 GT Avalanche Expert in the selected sizes.
Front travel is fork suspension stroke, not rear-wheel travel.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Gearing unavailable for this size.
Lowest0.65:1Highest3.27:1Total range506%
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.
