Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Identity & price
These bicycles are categorized differently: 2004 GT Chucker 2.0 is Mountain; 2006 GT Chucker 2.0 is BMX.
- Data limitation
No geometry is recorded for 2004 GT Chucker 2.0 and 2006 GT Chucker 2.0.
- Gearing
2006 GT Chucker 2.0 has a 38% lower climbing ratio than 2004 GT Chucker 2.0.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Equipment

Front travel is fork suspension stroke, not rear-wheel travel.

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.

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.
