Key differences

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

  1. Data limitation

    No geometry is recorded for 2008 Felt B12 and 2009 Felt B12.

  2. Gearing

    2009 Felt B12 has a 8% lower climbing ratio than 2008 Felt B12.

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

  3. Identity & price

    2008 Felt B12 had an original MSRP $400 lower than 2009 Felt B12.

    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.

2008 Felt B1253/39T · 11–23T · 10-speed
Lowest1.70:1Highest4.82:1Total range284%
Estimated speed at 90 RPMLowest gear11.9 mphHighest gear33.9 mph

Uses front tire 700C×23; rear size isn’t listed.

2009 Felt B1253/39T · 12–25T · 10-speed
Lowest1.56:1Highest4.42:1Total range283%

Speed unavailable: wheel or tire size is missing or unclear.

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.
