Key differences

Supported differences are shown below. Data limitations are labeled separately.

  1. Data limitation

    No geometry is recorded for 2011 GT Avalanche Expert and 2007 GT Avalanche Expert.

  2. Gearing

    2011 GT Avalanche Expert has a 6% lower climbing ratio than 2007 GT Avalanche Expert.

    A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.

  3. Equipment

    2011 GT Avalanche Expert has 10 mm more front travel than 2007 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.

Uses front tire 26×2.1; 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.
