Ride without worries

The P1.18 is a reliable partner on all continents under the harshest conditions. High mountains, deserts or coastal landscapes. Pure travelling pleasure: the P1.18 simply works – maintenance-free and permanently optimal function. Extreme climates, stone impact, sand, water and many thousands of miles cannot affect the P1.18. The huge ratio bandwidth combined with the even and very finely spaced gear steps permits comfortable travel over long distances with the pedalling rate that you find most comfortable.
The latest Pinion generation now offers even more shifting comfort. We have further optimised shift latches and cam shafts. as a result, shifting has become even smoother. The result: comprehensively silky-smooth running without any clicking noises in any of the 18 gears.

p1.18 ratio calculator

Ratio calculator for calculating the optimal secondary ratio for your Pinion P1.18 bicycle with chain or belt drive

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.
