Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Frame geometry
2022 Rocky Mountain Altitude Alloy 70 Coil has 9 mm more reach than 2024 Rocky Mountain Altitude Alloy 70 Coil in the selected sizes.
More reach puts the head-tube reference farther forward, not necessarily the hands.
- Handling
2024 Rocky Mountain Altitude Alloy 70 Coil has a 2.4° slacker head-tube angle than 2022 Rocky Mountain Altitude Alloy 70 Coil in the selected sizes.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Data limitation
Published weights cannot be compared because the measurement conditions are missing or differ.
Selected-size geometry
Geometry overlay
Frames share one scale and a bottom-bracket alignment. Size labels differ by brand; schematic drawing aids are identified below.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.

Speed unavailable: wheel or tire size is missing or unclear.
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.
