Key differences

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

  1. Data limitation

    No geometry is recorded for 2007 Giant TCR.

  2. Gearing

    2007 Giant TCR has a 22% lower climbing ratio than 1998 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 $300 lower than 1998 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.

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.

Historical specifications are presented as an archival reference. Components may have varied by market, size, or production run. Legacy reference geometry is model-level historical data whose corresponding frame size is not identified; compare those dimensions as reference values rather than size-normalized fit data.
