Lowest gear

29.0 gear inches

This value is within the central range for this class.

Cohort: Road / Aero Model year: 2027
Sample: 99 bicycles with this information
Coverage: 92.5% of the class

Highest gear

131.8 gear inches

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

Cohort: Road / Aero Model year: 2027
Lowest gear: 99 bicycles with this information, 92.5% of the class
Highest gear: 99 bicycles with this information, 92.5% of the class
