Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2005 Rocky Mountain ETSX-30.
- Data limitation
Only 2003 Rocky Mountain ETSX-30 has enough published drivetrain data for gearing calculations.
- Equipment
2005 Rocky Mountain ETSX-30 has 30 mm more front travel than 2003 Rocky Mountain ETSX-30 in the selected sizes.

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.
