“A 2-speed hub that solves the issues of both 1x and 2x drivetrains.

The opportunity to reduce aerodynamic drag, improve shift performance, and reduce the potential for dropped chains all without adding weight seems like a no-brainer”.
— Cycling Weekly

“It’s so quick it takes you by surprise, with none of the delay of even the very best front mechs”.
— Bike Radar

“One of the most intriguing products
we’ve seen in recent years”
— Rouleur

Powershift Technology is a wireless shifting technology that allows you to shift gears instantly and under full load. Its first application is the Powershift hub, which replaces the front derailleur. The Powershift hub offers unrivalled shift quality, high gearing range and small steps in between gears combining the benefits of both 1x and 2x.

No small chainring.

Avoid 45% higher chain forces. Bigger is better.

Less cross chaining.

Increase efficiency by straighter chainlines

No front derailleur.

Significantly reduce aero drag

How it works

Shift Button

A shifter or a satellite shift button will trigger a shift and is attached to the Smart Handlebar Unit, sending out a wireless signal.

Smart Thru Axle

The Smart Thru Axle receives the wireless shift signal and will trigger the hub to shift using contactless energy transfer.

Powershift Hub

The Powershift hub, when receiving the signal, will shift between 2 ratios. Read more about gear ratios.

How efficient is the hub?

Very efficient! More efficient than a 1x setup and as efficient as a 2x setup. Compared to a 1x, less cross chaining is required, sprocket and chainring sizes are larger and thus chain tension, crank and hub bearing losses are lower. Compared to a 2x; the fact that the 0.7 ratio of the hub still uses the large chainring in front, results in 30% less chain tension and thus lower chain, crank and hub bearing losses. On top of this you will experience that you will use the Classified hub much more frequent than a normal front derailleur, this means that in practice you will have less cross chain losses. The hub does not have any additional losses on in the 1:1 ratio, and is designed to have extremely low losses in the 0.7 ratio which are completely balanced out by the big chainring and straighter chainline by using a Classified setup.

What is the durability?

The Classified hub has an operational lifespan exceeding the lifespan of a bicycle’s internal systems, and it requires no maintainance.

Bearings are subject to normal wear and can be replaced.

If for any reason you think your Classified product isn't performing as it did when it was new, contact us and we will get you back on two wheels as soon as possible.
(See service & spare parts)

What maintenance is required?

None. The hub's internals are desiged to be maintainance-free.

Wheel bearings are, however, subject to wear as with any other hub, and can be replaced. If you experience play on your Classified hub, contact us and we will get you back on your bike as soon as possible (see service & warranty terms).

Can I shift under load?

Yes, Classified is unique as it can shift under load. You do not have to hold back, or stop pedaling to shift. It is designed to shift even under loads of up to 1000 watts. Futhermore, you can shift while coasting (and back pedaling). And even when standing still - the hub will complete the shift as soon as you start rolling. This all means faster, trouble-free shifting each time, over and over again.

Why does it only have 2 gears?

By offering 2 gears in combination with a regular derailleur setup, we can offer both a wide range and small gear steps just like you're used to. But by removing the front derailleur you get the dependability and performance you've always wanted.

Our goal is to optimise the drivetrain for performance. This means efficiency, durability and intuitive functionality. We see chain-based drivetrains as a solid platform to achieve this, but we want to remove its weakest link, the front derailleur, as it lacks dependability. Classified offers a wide gear range combined with small gear steps, which was only possible previously using a front derailleur. This is why the Classified hub is operated just like a regular 2x-setup.
