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.
