Lowest gear

29.0 gear inches

This value is within the central range for this class.

Cohort: Road / Race Model year: 2026
Sample: 720 bicycles with this information
Coverage: 78.6% of the class

Highest gear

131.8 gear inches

This value is within the central range for this class.

Lowest gear: 11.1 km/h
Highest gear: 50.5 km/h

Total gear range 455%

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: 29.0–131.8 gear inches
Class reference (p10–p90): 27.4–139.2 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Lowest gear: 720 bicycles with this information, 78.6% of the class
Highest gear: 720 bicycles with this information, 78.6% of the class
