What is the difference in speed between gearbox system, rohloff, pinion, shimano?

Introduction

Gearboxes are coming to be more and more popular on touring and bike packing bikes. The most popular form of bicycle gearbox is the inner gear hub, which has been used since the late 1800s. The first hubs were a two-speed structure, but these days we have the 14-speed Rohloff hub as our standard.

More previously you can discover crank-based gearboxes on touring bikes. The Pinion 18-speed gearbox is thriving in vogue and is now set up on touring bikes from additional than 90 factories.

While there is normally a burden penalty to gearbox systems over derailleurs, this is contradicted by how simple they are to retain, particularly in poor cycling situations. But let’s put the pros and cons of gearboxes aside for a second.

Gear range

Your bike’s gear range infers the speeds at which you can pedal your bike. Gear range offers us a notion for how susceptible it will be to ascend hills, cruise along on the flat and whether you’ll retain sufficient gearing to pedal on the downhill too.

A Rohloff retains a gear spectrum of 526% while the Pinion offers 636% which is the largest gear range for any type of bicycle.

Wielding a Rohloff hub with a low drive ratio, you can comfortably pedal up a hill at 5KPH in the freshest gear. When you switch to the biggest gear, you will top out at about 40KPH. The Pinion gearbox, with its additional 21% gear range, gives 20% more top-end speed so you can still pedal right up to 55KPH.

So with this in mind, you’re best to select one of the gearbox systems established on your budget and whether the gear range gave is adequate for the terrain you ride.

Drive Noise

The Rohloff hub is popular for eliciting noise in some of its gears, in specific, gear seven. The Pinion gearbox is not quiet it still brings about a slight whirring sound but it’s less conspicuous, mainly in the lower half of the gear range.

Gear pickup

Gear pickup deduces how soon your drivetrain immerses when you begin pedalling. On most bikes, you’ll see a small clunk when you pertain energy to the pedals, which is normally the pawl system in your rear hub engaging. Ideally, we need instant engagement, but bike hubs usually give between 24 to 36 engagement points at each wheel revolution.

The Rohloff and Pinion amass a different amount of engagement points banking on the gear assigned. The Rohloff has the most engagement points of the two between 17 and 55 while the Pinion has between 15 and 22.

But the Pinion gearbox similarly requires to engage at the rear hub when you pedal, so ideally, you’ll need a hub with the ample engagement points apparent to reduce any drivetrain slop. The Onyx hub wins this tournament with its instant-engagement sprag clutch method.

Shifting

When you shift gears with the Rohloff shifter, there are differing degrees of shifting resistance as you engage several categories of the gearbox. The Pinion shifter has a lighter shifting effort across all gears, rendering it a bit easy to use.

Conclusion

As the Rohloff hubs do not need a specially-designed frame, there are sufficient adapter fixtures so that the hub will fit virtually any bike. That compels them to the perfect retrofit if you’re glancing for a low-maintenance drivetrain.

  1. The Pinion has a few additional shift options now.
    I use a Pinion C.12 with the Cinq.de underbar levers on my hardtail mountainbike.
    Drop bar options also available for the Pinion too: https://cinq.de/en/shifting-technology/

    Any thoughts on looking into the Kindernay hub, 14 gears, hydraulic underbar shifters and swappable hubshells (https://kindernay.com/products/complete-gear-hub/product-landing-kindernay-xiv) as a Rohloff competitor…and keep an eye out for the new Pinion frame compatible Effigear Mimic that was launched this week (9spd, 469% range, underbar, twist and drop bar shift options).

    All the best,
