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…
Categorised Powershift 2x inside gear MTB hub for Shimano & SRAM
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.
Vital to notice: the brand new 10-40T cassette can be appropriate with the unique 12x142mm Categorised Powershift hub bringing greater 12sp gravel gearing choices to current customers, too.
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.
Additionally new however fairly apparent, the brand new MTB system is Increase spaced, which implies it isn’t a direct swap with different Powershift internals. However you do get wider rear hub & 12x148mm axle spacing, wider bearing spacing, and compatibility with virtually all fashionable mountain bikes.
Tech particulars
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.
Weights for the system are claimed at 485g for the Powershift Increase MTB inside gear hub, 72g for the Good axle, 125g for the 28-hole straight-pull centerlock disc brake hub shell OR 165g for the 32h j-bend 6-bolt disc shell, 24g for the Bluetooth Ringshifter, and 248g for the 12-speed 11-40T cassette. The Shimano AND SRAM appropriate cassette consists of the next gear steps: 11-12-13-14-15-17-19-22-25-29-34-40.
