Local importer Omnico have just been appointed as the Southern African distributor for Classified and are massively excited about the prospects this technology brings to our market. Today Classifed announce the launch of a mountain bike-specific Powershift hub system. Find out more about the Belgian drivetrain technology company and development of their groundbreaking Powershift hub below.

Classified announces today the launch of a mountain bike-specific Powershift hub system. The new mountain bike product, the Powershift boost hub, together with Classified’s new 11-40t 12 speed cassette, has a gear range of 530%, the largest of any drivetrain system on the market. Entry into the mountain bike space allows Classified to introduce yet another revolutionary piece of technology: the Ringshifter. A feather light wireless shifter that controls the 2 speed Powershift hub, offering sensational feedback and fitting seamlessly into the existing cockpit.

Known in the road and gravel world as the ‘front derailleur killer,’ Classified now reveals the secret ingredient to take existing 1×11 or 1×12 MTB drivetrain systems to the next level. Thanks to the 2 speed Powershift hub, Classified can offer a significantly higher gearing range with smaller steps in between each gear to maintain optimum cadence, whilst also offering the ability to Powershift; a 150 millisecond gear jump in either direction. As with the award-winning road and gravel hub, this instantaneous ‘Powershift’ can be done under full load of up to 1000 watts.

Updating the MTB Lexicon with a new verb

to Power·shift [Powershifting] {Verb}:
(also: the new benchmark in shifting gears)

  1. To shift gears under full load within 150 milliseconds
  2. Maintain valuable momentum during climbs and transitions, or before an attack
    Classified’s unique 2 speed gear hub allows riders to jump through 46% percent of the gear range, or the equivalent of 2 or 3 rear derailleur shifts, within 150 milliseconds. As such, ‘Powershifting’ is quickly becoming the go to term for maintaining momentum on the trails.

Tests undertaken with pro riders showed a far greater use of the Powershift hub gear as opposed to the rear derailleur, leading to an overwhelming increase of momentum through transitions.

“The feedback of professional riders is very promising and brought us even better insights into the enormous potential the product offers. Extending our range further into off-road space with the mountain bike hub confirms Classified’s vision to be a technology that is compatible across all cycling disciplines. We are extremely excited about the possibilities the new product brings and its ability to enhance the existing MTB drivetrain market.” says Mathias Plouvier, CEO and co-founder of Classified Cycling.

CTO Roell van Druten adds “we are very proud to bring Powershift technology to mountain biking. With an ultimate gear range of 530%, the Powershift Boost hub combines a high-grade, one-piece compact steel cassette (11-40t) with a larger chainring, improving the overall durability of the drivetrain.”

Van Druten goes further to explain the benefits of the new system: “Using the Classified hub with an 11-40t cassette and a 34t chainring results in the lowest drivetrain ratio of 0.58. To achieve this ratio with a traditional system the user would have to use a 30t chainring. Using a smaller chainring in a traditional system lowers the efficiency and durability of that system due to the higher chain forces. The more compact Classified cassette also allows the use of a shorter derailleur cage, increasing the robustness of the drivetrain alongside the efficiency.”

The Ringshifter

The next generation of shifting, this sleek, fully wireless handlebar control provides unrivalled shifting performance with the lightest flick of your thumb. The Ringshifter can perform 10,000 shifts before needing to be easily recharged with the provided magnetic USB cable.

Featuring a unique magnetic spring back mechanism, the Ringshifter delivers unparalleled durability and a smooth, responsive feel. The functionalities of the Ringshifter can be customized to meet the individual needs of every rider.

Doubling the number of gears?

The MTB world has become used to a 1×11 or 12 gear drivetrain system but Classified passionately believe that more is needed for the optimum ride experience. The addition of the 2-speed hub, multiplying the cassette gears and gearing range, gives the rider 16 unique gears, after removing duplicate ratios, to always be able to access the right cadence, reduce gear grinding and remove huge gear steps. On top of that the additional gears are all accessible in the middle of the cassette which helps keep cross chaining to a minimum.

Classified’s 11 – 40t, 12 speed cassette is also compatible with the existing 142mm variant of the Powershift hub, ideal for extreme gravel riding or bikepacking, where an extensive gear range and compact steps in between each gear are required to ensure a comfortable cadence.

Pricing and availability

The Classified Powershift boost hub has a build-in width of 148mm and is mounted using the supplied 12mm thru-axle that wirelessly connects with the Ringshifter. The Powershift boost hub will be available to purchase in three ways through Classified’s worldwide network of dealers and distributors from May 23, 2023. The Powershift boost hub can be fitted to any mountainbike frame with a 148mm dropout spacing.

• Powershift hub set + Classified hookless carbon wheelset €2,699
• Powershift hub set with hub shell €1,549
• Powershift hub set without hub shell, €1,449
*(MSRP in Europe)

Local pricing and availability dates TBC- pricing expected to be in line with international.

The Powershift hub will be available to buy with Classified’s new M25/30 hookless carbon wheelset. With an internal rim width of 30mm, combined with a 25mm high rim profile, the M25/30s have been developed to deal with every kind of off-road terrain.
The dedicated hub shell design can be purchased in 28 hole straight pull and 32 hole J-bend spoke options, allowing customers to combine the proprietary hub with any of the Classified wheel partners, or to build their own wheels as they see fit.

Yoh.... Mechanical doping at SS world champs is going to be a thing!

This is pretty rad though.

I know SRAM used to have a 2 speed hub that shifted automatically based on the rotational speed of the hub shell and CSS also imported an internal 3 speed hub that had an 8 speed cassette on the freehub body, so it's been 'a thing' before.

The electronic shifting and more refined system and looks is impressive though. This is an interesting segment in the market and I'm not surprised someone is trying to refine and corner it

I don\'t really get it for mountain biking - it just seems like an old 2x setup albeit with faster shifting. But I like the idea of this on a single speed setup. That would be fun.

'Single speed'..... 🙊

I think this IS a direct replacement for a 2x groupset. They specifically mention gravel bikes 

It's 1x gear simplicity with either a bail out or a granny. Which ever way you want to wield it I guess.

"this instantaneous ‘Powershift’ can be done under full load of up to 1000 watts." Well I'm sorry but that's a deal-breaker for me. #unit.

i've been after classified for over 2 years.

think it was first awarded to cape cycles who did nothing with it. (i stand to be corrected)

massive delays with ICASA registration to.

glad someone has it now and is doing something with the product - not so excited its Omnico as i've had more than a few warranty issues with them. not to mention stock issues.

but lets hope thats in the past

 

an extremely cool product and i really think it could revolutionise cycling

Yikes the price is eye watering. Definitely not going to be for a bodge build! However I would definitely like this kit. One could use a 1x specific gravel rear derailleur for clearance and a larger chainring . Efficiency will be somewhere around 93% though due to the drivetrain losses in the epicyclic drive. In the Mtb application this is less of a problem than in a road bike application

Expensive and less efficient? (although once you're in the mud I guess the efficiency thing falls away).

I'm sure you'll see a few around, but I suspect you cover the same ground with a 12s or a 13s drivetrain (assuming no-one is going 2x13) - I doubt you get much in added gear range or tighter ratios between 2x11 on a classified hub vs a 1x13.

not sure where you got the efficiency figure from?

granted this is their own data - would be interesting to see 3rd party data on it

their efficiency figures are meaningless because they measure at<50W . Who rode with that little power and torque (rpm is high)

epicyclic drives usually have a 2-3% efficiency loss per stage and I assume for a 2 speed system it’s 3stages (sun, planets , ring gear and arm). So best case is 6% loss x chain losses which I assume to be 99% efficient under ideal conditions.

0.99x0.94 =0.9305

or 93.05% efficiency 

bit like I said on an Mtb we are less

Concerned about the efficiency because of the changing conditions the drivetrain operates under in normal working conditions. Just pointing out their efficiency shown is not real world I believe

Can someone explain what this is to the average joe on the street that does not have a masters degree in engineering?

Hambini has already done a hatchet job and panned the efficiency loss caused by the hub. That said I still don\'t understand what it is :-)

they have hidden an extra (planetary gear) 'gearbox' in between the cassette and the hub.

you can either ride this 'fixed' which then works like a normal 1x setup, or 'free' where it adds a step-down ratio between the cassette rotation and the hub rotation (cassette rotates faster than the hub). This acts like being in the small chainring gear.

But to Hambini's point you then have an efficiency loss in the new step-down gear. I think he used 97% efficient for the 'fixed' arrangement, and 97% of 97% for the 'free' setting. the extra ~3% loss is about 10w out of your 400W peak power output

Basically if the input force is 100N the output gear will deliver a force of  93N.

torque is a different matter but basically it will be 93% less than what the calculated value would be for the gear ratio.

Friction losses inside the hub are higher than for a normal chain drive.

what would it be for a traditional drivetrain?

Generally around 99% to 97% depending on the environmental conditions. There are circumstances where the planetary system is more efficient.

chain drives can dip as low as <90%

to be fair to Classified they have come up with an innovative solution to address the limits of 11s drivetrains.  But SRAM came out with 12s, and that mostly addressed those issues anyway, and all the okes who could afford Classified went 12s long ago.

Planetary would be more efficient than a front deraileur caked with cane field mud, but thats about it.

But this makes it 22 or 24 speed?

Solving 1 perceived problem (the front derailleur) with a multiple of others. All things being equal, a couple of obvious negatives that come to mind:

  • Mechanically, it has more parts and is significantly more complicated that a standard hub and front derailleur combination
  • The planetary gears in the Classified hub has to be less efficient than a standard hub
  • It forces one to cross chain, which is again less efficient 
  • It is proprietary, if you break a wheel you have a problem 
  • It is not clear to my how one integrates it into an existing ecosystem (e.g.DI2, AXS, EPS)
  • It is significantly heavier than a standard freehub 
  • It is really expensive compared to the alternatives

In summary it a proprietary solution that is more complicated, less efficient and heavier than the obvious alternative.

The only question I have is why?

They perceive cyclists as a gullible market, always ready to spend bug bucks on the next "big thing". I wonder where they got that idea from? SRAM perhaps? 🙂

In a 2x drivetrain you generally only use a little more than half the cluster with each chainring - so you have maybe 2x7 = 14 ratios that you regularly use with a 2x11 drivetrain. (vs 12 ratios in a 1x12 drive)

You're trying to solve 3 issues really - 

The range of gears available - SRAM Eagle has a 520% range on a 10-52 cassette, Classified are advertising 534% as their top end option.

The size of the steps between the gears - and 2x drivetrains do have an advantage here. Eagle will have steps of 15-20% increases between gears, Classified will have maybe 10%-15% steps.

Weight - and Eagle is proabably lighter? I haven't checked.

The game changer is for Gravel & Road with being able to run a NW chainring on the front with the same/similar range. No chain drops on the front etc. 

If running di2, it will fit in to the lever just like the FD would, so seamless. AXS, there is no integration yet, so they offer a button that can be fitted anywhere like a sram BLIP button. 

There is a bunch of teams on the WT using this system already.

A chain catcher can achieve exactly the same outcome, it attaches to the front derailleur hanger, has no moving parts, weighs basically nothing, is really cheap and most importantly works.

Even when Wout van Aert rode SRAM 1x during the 2023 Milan San Remo, he still used a chain catcher.
