If you want automotive quality, worry free durability and a super silent ride, then you better choose a gearbox mountain bike. Let us give you a few other reasons.
The gearbox mountain bike drivetrain gives you more control as your rear wheel is lighter. That means more grip, more confidence.
The magnesium Pinion gearbox is almost maintenance free and eliminates the risk of bending or breaking your derailleur.
Shifting a Pinion mountain bike is up to five times quicker then shifting a derailleur bike. And you can even shift when coasting or standing still. It takes a few hours to get used to, but gearbox shifting is surely a big step forward.
With the gearbox mtb drivetrain you will have a huge 600% gear range, 20% more than an SRAM Eagle 1×12 10-50t layout.
The Pinion C1.12 provides equal gear steps throughout all gears making your selected gear ratios more predictable than ever.
Studies have shown that the efficiency of the Pinion drivetrain ranges from 91% in the heaviest gear to 98% in granny gear.*
For comparison, a derailleur layout, under perfect ‘laboratory’ circumstances, has an efficiency of 93% to 98%**. However when dirt comes into play and builds up the efficiency tends to drop a good few percent.
A major benefit of the gearbox drivetrain is the straight, constant chainline, ensuring great efficiency between chainring and rear wheel. This in contrast to derailleur layouts where cassettes seriously compromise the chainline at either end of the cassette.
Pinion gearboxes are used all over the world, in all conditions no matter how challenging. They have proven their robustness in numerous round-the-world rides. Ice cold temperatures at the Arctic Circle or sweltering desert heat do not present a problem for these transmissions.
High altitudes, humid conditions or even the occasional transfer through a river is not a problem either if you occasionally check and make sure the inside of the gear shift box remains well greased.
