  1. Data limitation

    No geometry is recorded for 2012 Diamondback Overdrive Comp and 2011 Diamondback OVERDRIVE COMP.

  2. Gearing

    2012 Diamondback Overdrive Comp has a 11% lower climbing ratio than 2011 Diamondback OVERDRIVE COMP.

    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.

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.
