Gearing

Estimated speeds at 80 rpm

Lowest gear: 12.8 km/h
Highest gear: 32.6 km/h

Total gear range 255%

Technical details and class reference

These speeds describe the gearing at the selected cadence, not how fast you can ride.
Calculated from published gear-inch values and their wheel-size assumptions.
These gearing values describe the bicycle, not a selected frame size.
A 100% range means one ratio; 500% means the highest ratio is five times the lowest.
For e-bikes, motor assistance cutoff is not represented.

Gear-inch range

Lower gear-inch values travel less distance per pedal revolution; higher values travel farther.

This bicycle: 33.4–85.0 gear inches
Class reference (p10–p90): 33.4–103.9 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Cohort: Mountain / Downhill Model year: 2019
Lowest gear: 87 bicycles with this information, 93.5% of the class
Highest gear: 87 bicycles with this information, 93.5% of the class
