Key differences

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

  1. Data limitation

    No geometry is recorded for 2007 Giant TCR and 2004 Giant TCR.

  2. Gearing

    2007 Giant TCR has a 16% lower climbing ratio than 2004 Giant TCR.

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

  3. Identity & price

    2007 Giant TCR had an original MSRP $500 lower than 2004 Giant TCR.

    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.

2007 Giant TCR50/34T · 12–26T · 9-speed
Lowest1.31:1Highest4.17:1Total range319%
Estimated speed at 90 RPMLowest gear9.2 mphHighest gear29.3 mph

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

2004 Giant TCR53/39T · 12–25T · 9-speed
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.
