Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Frame geometry
2023 Rocky Mountain Slayer Carbon 70 has 66 mm more reach than 2021 Rocky Mountain Slayer Carbon 70 in the selected sizes.
More reach puts the head-tube reference farther forward, not necessarily the hands.
- Frame geometry
2023 Rocky Mountain Slayer Carbon 70 has 25 mm more stack than 2021 Rocky Mountain Slayer Carbon 70 in the selected sizes.
More stack places the frame reference higher, not necessarily the handlebar.
- Handling
2023 Rocky Mountain Slayer Carbon 70 has a 0.8° slacker head-tube angle than 2021 Rocky Mountain Slayer Carbon 70 in the selected sizes.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Identity & price
2021 Rocky Mountain Slayer Carbon 70 had an original MSRP $1,010 lower than 2023 Rocky Mountain Slayer Carbon 70.
Original MSRP is the published list price when new, not today’s used-bike value.
- 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.
