Categorised’s two-speed internally geared Powershift hub brings 2x drivetrains again to mountain bikes with one new 12-speed MTB hub that works for each Shimano & SRAM drivetrains, plus new Increase-spaced hubs and a tiny wi-fi thumb shifter. That’s proper, with wi-fi digital shifting and only one 11-40T Categorised cassette, Powershift will bump up your MTB gearing vary to 530% whether or not you might be driving a Shimano 12sp or SRAM Eagle 1x drivetrain…

Very like we’ve seen on highway and gravel, the wi-fi Powershift hub brings lightning-fast digital entrance shifts again to fashionable 1x bikes with all of the chainline and chain retention advantages of a single chainring setup, but with the smaller gearing steps and wider total gearing of a conventional 2x drivetrain. And you may shift beneath load whereas pedaling, to successfully drop or improve your gearing instantaneously such as you would in 2 or 3 common rear derailleur shifts. That’s particularly useful on the mountain bike when you may be popping out of a technical nook or hitting a steep technical climb, and may hit that prompt gear shift…
What’s new?

Inside, the Categorised Powershift MTB hub is successfully unchanged. Positive, Categorised assures that the internals, axle, bearings & seals have all been upgraded to deal with the more durable lifetime of a mountain bike, however the practical bits are the identical idea: a 1:0.68 ratio planetary discount gear, a wi-fi digital controller ultimately of the Good axle that doesn’t should be recharged, and a wi-fi distant shifter you can neatly combine into your current cockpit setup.

The obvious new bit is Categorised’s new proprietary one-piece machined metal 11-40T cassette that works with each Shimano 12sp and SRAM Eagle 12sp derailleurs and chains. Categorised says it’s a blissful medium between the 2 drivetrains, and whereas it takes slightly bit extra finetuning for its preliminary setup, as soon as tuned they are saying it shifts nice with both drivetrain. Pairing the 11-40T cassette with the interior discount gear permits mountain bikers to measurement up their chainring by about 10-15% whereas getting each simpler AND more durable gears because of the system’s broad 530% gearing vary.

The opposite large new factor is the tiny Ringshifter distant… not so in contrast to the Zirbel twist shifter in observe – simply spin the paddle along with your thumb to shift. However the Categorised Ringshifter distant is totally self-contained and wi-fi – and rechargeable with a proprietary USB dongle after 10k shifts – making it extremely fast to put in in between your grip and brakes.

Categorised says Powershift MTB 12sp delivers 16 distinctive gears (after factoring out duplicate ratios) with a little bit of a mixture of derailleur & hub shifting. That’s with the ‘new’ gears successfully in the midst of the cassette block for higher chainline, and bigger cogs/chainrings total (extra tooth) for improved drivetrain rolling effectivity. They are saying these greater cogs and the truth that the cassette is machined metal additionally imply longer drivetrain sturdiness.
