Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Frame geometry
2019 Specialized Rockhopper Comp has 16 mm more stack than 2024 Specialized Rockhopper Comp in the selected sizes.
More stack places the frame reference higher, not necessarily the handlebar.
- Handling
2024 Specialized Rockhopper Comp has a 1.8° slacker head-tube angle than 2019 Specialized Rockhopper Comp in the selected sizes.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Data limitation
Only 2019 Specialized Rockhopper Comp has enough published drivetrain data for gearing calculations.
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.

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.
