Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Handling
1993 Ross Mt. St. Helens has a 0.5° slacker head-tube angle than 1997 Ross Mt. St. Helens in the archived geometry. Frame size is not identified for 1997 Ross Mt. St. Helens and 1993 Ross Mt. St. Helens.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Gearing
1997 Ross Mt. St. Helens has a 15% lower climbing ratio than 1993 Ross Mt. St. Helens.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
1993 Ross Mt. St. Helens had an original MSRP $251 lower than 1997 Ross Mt. St. Helens.
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.
