Technical analysis

3 measures

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

Front travel

150 mm

This value is below the central range for this class.

Cohort: Mountain / Enduro Model year: 2026
Sample: 1,332 bicycles with this information
Coverage: 95.2% of the class

Rear travel

150 mm

This value is within the central range for this class.

Cohort: Mountain / Enduro Model year: 2026
Sample: 1,005 bicycles with this information
Coverage: 71.8% of the class

Shifting

Electronic

454 of 1,399 bicycles with this information use electronic shifting.

Cohort: Mountain / Enduro Model year: 2026
Sample: 1,399 bicycles with this information
Coverage: 100.0% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 7.1 km/h
Highest gear: 35.5 km/h

Total gear range 500%

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: 18.6–92.8 gear inches
