Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Frame geometry
2021 Specialized S-Works Epic has 12 mm more reach than 2019 Specialized S-Works Epic in the selected sizes.
More reach puts the head-tube reference farther forward, not necessarily the hands.
- Handling
2021 Specialized S-Works Epic has a 2.0° slacker head-tube angle than 2019 Specialized S-Works Epic in the selected sizes.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Identity & price
2019 Specialized S-Works Epic had an original MSRP $1,980 lower than 2021 Specialized S-Works Epic.
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.
