Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Identity & price
These bicycles are categorized differently: 2021 Cannondale Quick 4 is Hybrid; 2020 Cannondale Quick 4 is City & Commuter.
- Frame geometry
2020 Cannondale Quick 4 has 24 mm more stack than 2021 Cannondale Quick 4 in the selected sizes.
More stack places the frame reference higher, not necessarily the handlebar.
- Handling

Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.

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.

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.
