Technical analysis

4 measures

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

Front travel

120 mm

This value is within the central range for this class.

Cohort: Mountain / Trail Model year: 2025
Sample: 1,810 bicycles with this information
Coverage: 97.5% of the class

Lowest gear

17.8 gear inches

This value is below the central range for this class.

Cohort: Mountain / Trail Model year: 2025
Sample: 1,384 bicycles with this information
Coverage: 74.6% of the class

Highest gear

90.0 gear inches

This value is within the central range for this class.

Cohort: Mountain / Trail Model year: 2025
Sample: 1,384 bicycles with this information

Cohort: Mountain / Trail Model year: 2025
Sample: 1,849 bicycles with this information
Coverage: 99.6% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 6.8 km/h
Highest gear: 34.5 km/h

Total gear range 506%

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: 17.8–90.0 gear inches
Class reference (p10–p90): 17.1–98.6 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Cohort: Mountain / Trail Model year: 2025
Lowest gear: 1384 bicycles with this information, 74.6% of the class
Highest gear: 1384 bicycles with this information, 74.6% of the class
