- Data limitation
No geometry is recorded for 2007 GT El Centro 16 and 2011 GT El Centro 16.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM

Uses front tire 16×2.125; rear size isn’t listed.
Ratio2.36:1
Estimated speed at 90 RPMGear
Uses front tire 16×2.25; 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.
