Front travel

130 mm

This value is within the central range for this class.

Cohort: Mountain / Trail Model year: 2017
Sample: 429 bicycles with this information
Coverage: 95.7% of the class

Lowest gear

22.1 gear inches

This value is above the central range for this class.

Cohort: Mountain / Trail Model year: 2017
Sample: 416 bicycles with this information

Gearing

Estimated speeds at 80 rpm

Lowest gear: 8.5 km/h
Highest gear: 35.5 km/h

Total gear range 420%

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: 22.1–92.8 gear inches
Class reference (p10–p90): 16.8–94.9 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Cohort: Mountain / Trail Model year: 2017
Lowest gear: 416 bicycles with this information, 92.8% of the class
Highest gear: 416 bicycles with this information, 92.8% of the class
