Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Frame geometry
2015 Specialized Allez Elite has 7 mm more reach than 2021 Specialized Allez Elite in the selected sizes.
More reach puts the head-tube reference farther forward, not necessarily the hands.
- Frame geometry
2021 Specialized Allez Elite has 23 mm more stack than 2015 Specialized Allez Elite in the selected sizes.
More stack places the frame reference higher, not necessarily the handlebar.
- Gearing
2021 Specialized Allez Elite has a 13% lower climbing ratio than 2015 Specialized Allez Elite.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
2015 Specialized Allez Elite had an original MSRP $350 lower than 2021 Specialized Allez Elite.
Original MSRP is the published list price when new, not today’s used-bike value.
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.

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.
