Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
Only 1999 Rocky Mountain Instinct has enough published drivetrain data for gearing calculations.
- Identity & price
1999 Rocky Mountain Instinct had an original MSRP $331 lower than 2001 Rocky Mountain Instinct.
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.
Gearing unavailable for this size.

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.
