Technical analysis

2 measures

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

Front travel

100 mm

This value is within the central range for this class.

Cohort: Mountain / Cross-country Model year: 2025
Sample: 1,508 bicycles with this information
Coverage: 87.8% of the class

Shifting

Mechanical

222 of 1,648 bicycles with this information use electronic shifting.

Cohort: Mountain / Cross-country Model year: 2025
Sample: 1,648 bicycles with this information
Coverage: 95.9% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 7.2 km/h
Highest gear: 30.3 km/h

Total gear range 418%

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: 18.9–79.1 gear inches
