- Data limitation
No geometry is recorded for 2008 Sun Bicycles Retro Alloy and 2001 Sun Bicycles Retro Alloy.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.

Ratio2.33:1
Estimated speed at 90 RPMGear
Uses front tire 26×2.125; rear size isn’t listed.
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.
