Nine gears offer a bandwidth of 568%. Fast and efficient shifting is made possible by the large gear gradation of 24.3%. In combination with powerful rear wheel electric motors, the C1.9XR shows its advantages: Quiet, virtually maintenance-free and durable. In the MTB enduro use, the C1.9XR offers an enormous range of gears with low weight at the same time.

THE C1.9XR-GEARBOX IN COMPARISON

"On muddy trails the fully sealed gearbox really delivers precise shifting and silky smooth operation while conventional derailleurs crunch and grind in protest."

C1.9XR Ratio Calculator

The Pinion gearbox calculator helps you to choose the ideal gearbox tuning. The internal gear ratio for each gear of all types of gearboxes is already defined in our calculator. The entire spectrum of a Pinion transmission can be shifted to fast or slow with the secondary ratio to the rear wheel. A 1:1 tuning is also possible by using sprockets of the same size or toothed belt pulleys.

Calculator is Available in only Desktop Mode

(Number of teeth chainring gearbox)
(Number of teeth sprocket rear wheel hub)
(Wheel circumference in mm)
(in mm)

Additional ground clearance compared to a derailleur gear system with a chainring with 44 teeth

The size ratio, or the ratio of the number of teeth between chainring and rear sprocket is called ratio. Together with the circumference of the wheel the unfolding can be calculated. The unfolding is the distance in meters or centimeters travelled by a bicycle with one crank rotation.

REAL GEARS
Real gears refer to the gear steps of a bicycle transmission that can be optimally used. In derailleur gears, the skewed running of the chain leads to significant losses of efficiency. In addition, when there are two or three front sprockets there will be redundant, i.e. equivalent, gears. A 3×10 derailleur transmission, for example, actually only offers 14 or 15 real gears from this perspective.
