Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Frame geometry
2021 Polygon XTRADA 7 has 20 mm more reach than 2026 Polygon XTRADA 7 in the selected sizes.
More reach puts the head-tube reference farther forward, not necessarily the hands.
- Frame geometry
2026 Polygon XTRADA 7 has 26 mm more stack than 2021 Polygon XTRADA 7 in the selected sizes.
More stack places the frame reference higher, not necessarily the handlebar.
- Data limitation
Only 2026 Polygon XTRADA 7 has enough published drivetrain data for gearing calculations.
- Identity & price
2021 Polygon XTRADA 7 had an original MSRP $100 lower than 2026 Polygon XTRADA 7.
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.
Gearing unavailable for this size.

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.
