Key differences

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

  1. Data limitation

    No geometry is recorded for 2010 Bianchi D2 Crono/Tri Alu and 2009 Bianchi D2 Crono/Tri Alu.

  2. Gearing

    2010 Bianchi D2 Crono/Tri Alu has a 7% lower climbing ratio than 2009 Bianchi D2 Crono/Tri Alu.

    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.
