Key differences

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

  1. Data limitation

    No geometry is recorded for 2007 Giant Trinity A0 and 2008 Giant Trinity A0.

  2. Gearing

    2007 Giant Trinity A0 has a 8% lower climbing ratio than 2008 Giant Trinity A0.

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

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.
