Key differences

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

  1. Data limitation

    No geometry is recorded for 2009 Felt B2 and 2011 Felt B2.

  2. Gearing

    2011 Felt B2 has a 7% lower climbing ratio than 2009 Felt B2.

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

  3. Identity & price

    2009 Felt B2 had an original MSRP $2,700 lower than 2011 Felt B2.

    Original MSRP is the published list price when new, not today’s used-bike value.

Gearing comparison

Lower gears help on climbs. Higher gears suit higher speeds.

RPM

RPM = pedal turns per minute.

Lowest1.56:1Highest4.42:1Total range283%
Estimated speed at 90 RPMLowest gear11.0 mphHighest gear31.1 mph

Uses front tire 700C×23; 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.
