- Identity & price
2007 GT El Centro 16 had an original MSRP $110 lower than 2009 GT El Centro 16.

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.
