Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2010 Kona Bass and 2009 Kona Bass.
- Data limitation
Only 2009 Kona Bass has enough published drivetrain data for gearing calculations.
- Identity & price
2010 Kona Bass had an original MSRP $300 lower than 2009 Kona Bass.

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.
