Technical analysis

3 measures

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

Lowest gear

34.8 gear inches

This value is within the central range for this class.

Cohort: Road / Triathlon Model year: 2021
Sample: 106 bicycles with this information
Coverage: 89.0% of the class

Highest gear

137.1 gear inches

This value is within the central range for this class.

Cohort: Road / Triathlon Model year: 2021

Shifting

Mechanical

71 of 119 bicycles with this information use electronic shifting.

Cohort: Road / Triathlon Model year: 2021
Sample: 119 bicycles with this information
Coverage: 100.0% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 13.3 km/h
Highest gear: 52.5 km/h

Total gear range 394%

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: 34.8–137.1 gear inches
Class reference (p10–p90): 34.8–145.0 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Cohort: Road / Triathlon Model year: 2021
Lowest gear: 106 bicycles with this information, 89.0% of the class
Highest gear: 106 bicycles with this information, 89.0% of the class
