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

  1. Data limitation

    No geometry is recorded for 2011 Jamis Dragon 29 Race and 2014 Jamis Dragon 29 Race.

  2. Gearing

    2014 Jamis Dragon 29 Race has a 11% lower climbing ratio than 2011 Jamis Dragon 29 Race.

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

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.
