Technical analysis

2 measures

How these figures sit among bicycles of the same class and model year. Context, not a ranking.

Lowest gear

51.6 gear inches

This value is above the central range for this class.

Cohort: Mountain / Cross-country Model year: 2014
Sample: 380 bicycles with this information
Coverage: 92.2% of the class

Highest gear

51.6 gear inches

This value is below the central range for this class.

Cohort: Mountain / Cross-country Model year: 2014
Sample: 380 bicycles with this information
Coverage: 92.2% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 19.7 km/h
Highest gear: 19.7 km/h

Total gear range 100%

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: 51.6–51.6 gear inches
Class reference (p10–p90): 17.3–113.5 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Cohort: Mountain / Cross-country Model year: 2014
Lowest gear: 380 bicycles with this information, 92.2% of the class
Highest gear: 380 bicycles with this information, 92.2% of the class
