This value is within the central range for this class.

Cohort: Road / Race Model year: 2025
Sample: 762 bicycles with this information
Coverage: 78.1% of the class

Highest gear

139.2 gear inches

This value is above the central range for this class.

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: 30.8–139.2 gear inches
Class reference (p10–p90): 28.2–139.2 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Cohort: Road / Race Model year: 2025
Lowest gear: 762 bicycles with this information, 78.1% of the class
Highest gear: 762 bicycles with this information, 78.1% of the class
