Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Frame geometry
2027 Scott Spark RC Pro has 13 mm more reach than 2026 Scott Spark RC Pro in the selected sizes.
More reach puts the head-tube reference farther forward, not necessarily the hands.
- Frame geometry
2026 Scott Spark RC Pro has 13 mm more stack than 2027 Scott Spark RC Pro in the selected sizes.
More stack places the frame reference higher, not necessarily the handlebar.
- Handling
2027 Scott Spark RC Pro has a 1.7° slacker head-tube angle than 2026 Scott Spark RC Pro in the selected sizes.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Identity & price
2026 Scott Spark RC Pro had an original MSRP $2,500 lower than 2027 Scott Spark RC Pro.
Original MSRP is the published list price when new, not today’s used-bike value.

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.

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.
