Technical analysis

2 measures

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

Front travel

203 mm

This value is above the central range for this class.

Cohort: Mountain / Downhill Model year: 2018
Sample: 93 bicycles with this information
Coverage: 92.0% of the class

Rear travel

210 mm

This value is within the central range for this class.

Cohort: Mountain / Downhill Model year: 2018
Sample: 96 bicycles with this information

Gearing

Estimated speeds at 80 rpm

Lowest gear: 15.2 km/h
Highest gear: 34.5 km/h

Total gear range 227%

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: 39.6–90.0 gear inches
