Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
Only 2003 Rocky Mountain Flow has enough published drivetrain data for gearing calculations.
- Identity & price
2004 Rocky Mountain Flow had an original MSRP $231 lower than 2003 Rocky Mountain Flow.
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.
