The Front Derailleur Killer? | Classified Powershift Hub Gear First Look
VloĆŸit
- Äas pĆidĂĄn 27. 06. 2024
- Does this mean the end for the front derailleur? Classified's new internal geared hub for road and gravel bikes, the Powershift, is a new look at internal hub gears for cycling. Si takes a ride on the wirelessly operated rear hub, which uses planetary gears to offer two different gear ratios, in addition to the use of an 11 speed cassette.

What do you think of this hot tech? Will it catch on?
I think it is ca tching on, with Rohloff, pinion, sram dual drive etc, there is a movement towards internal gears. We would see more and more of it, better efficiency and quality.
If the price is affordable for beginners,
That means we can mount giant chainring like 75t without worrying the FD max size capacity, usually 52t.
Then, that also means later, sprocket 11t - 50t chainring 37t - 75t combi might be possible
Now, how about cargo bike test for it durability?
Ù©(ââżâïœĄ)Û¶
I really like the look of this......hope it catches on and the prices come down a bit
Probably too expensive
I like the idea. It's too expensive for my taste but understandable for the start.
Questions:
The cassette mount, is this an open standard so other suppliers can provide parts?
Will there be a mechanical shifting option too? (not a fan of wireless shifters ...)
I can now brag to my mates I climb with the big chainring.
there is no big chainring if there is only one
@@Simon-le2jk There's no small chainring
đ definitely
Where are the guys obsessed with each ounce of wieght? I'm sure this will cost about as much as a down payment on a house .
your mates will be confused how are you spinning with a big chain ring. hahahaha.
New pre-ride routine by GCN: charge head unit, charge di2, charge powermeter, charge lights, charge whoop, charge tyrewiz, charge through-axle.
Now someone will need to design a common bicycle electrical system so everything can be powered by a single battery...
And their gopros, and the cameraman's gear.
@@Samwell314 Even better, by a hub dynamo. At least it's one electrical device that you don't need to charge! đ
And technically charge their tyres with air as well.
Charge legs!
Now fit it with double chainring and you get yourself 44 speed groupset.
Just need to figure out where to put the third shifter..
Agree - I would do so
11x46 cassette?
1x46 compliant derailleur?
Match with shifter brand?
@@rosskline a friction shifter on the barends...
@@fubarryk Used to be bar end friction shifters for touring bikes with hub gear trigger usually on downtube or top of handlebar- you could use twist grips but unreliable and astonishingly uncomfortable to use
As others have said, this stands out as a genuinely useful bit of innovation, and seems to address all the limitations of both 1x x 2x systems. Although beyond my budget, it doesn't seem ridiculously expensive either, given that the conversion kit includes a pair of carbon wheels. Hope this takes off and comes down in price in the future.
As a lifetime cross chaining enthusiast, this is really appealing.
Alright "cross chaining enthusiast" is now going on my resume, that's fantastic!
Agreed, I am never used the small chain ring! This would be excellent! Sadly if it requires disk brakes it's a no go for me
@@glharlorFinally you'll be able to enjoy the real brakes. Best regards, GMBN.
All of your problems are solved!
@@gcntech Where do I sign up to
1. get the certification for "cross chaining pro"
2. to sell a kidney to be able to afford this?
Now this is some tech that's actually groundbreaking and hopefully it catches on. Variations of this should cover pretty much all bike disciplines in the future
internal gear hubs have existed for 50 years
@@nick37781
But have they been good enough to actually use?
@@keirfarnum6811 Yes, they're extremely common in commuter and city bikes.
@@mikehall6608 have they been able to be used in conjunction with external gears simultaneously though?
@@raycath0de I'm not sure, but other comments below this video suggest they have.
Whenâs the time that GCN switches to E-Scooters for the camera vehicle?
i second the request
YES! That would absolutely be a good move!
Yes the motor is quite loud....get something quiet ALREADY
GCN should just mod their filming vehicle to have the exhaust come out somewhere not near the camera position
Back in days of old, some 2 speed hubs were wireless too. Kickback hubs were made by Bendix I believe, and you quite literally pedalled backwards slightly to shift between high and low.
Finally! Something that really looks like a technology-driven improvement for bike tech world. We didn't see this for some long time. I'm fascinated, personally. Si rocks as usual) ..
agree, a real improvement over the gimmick CS drivetrain years ago!!!no bs!
Agree, potentially the biggest innovation since di2.
It's crazy expensive dude!
Nothing a normal person can or wants to afford!
It's like putting a F1 beake system on your family car
â@@hmcredfed1836 Exactly, buddy. Great comparison - some decades ago f1 brakes were as powerful as fiat punto ones. And that's why fiat punto is able to confidently stop nowadays. Tesla was making only superexpensive electric supercars at the beginning of its history, and now we can afford model 3. That's how it works, and that's why progress is a good thing. cheers
even better if it s titanium or carbon fiber
Give it 6 months and AliExpress will have a Klassified hub!!
Yep, for 1/5th of the price, but one that breaks during or after the first season..

@@nmgn rumor has it it's open now?
@@iamruss74 Yep www.bbc.com/news/world-middle-east-56559904, at least on its way.

This reminds me of the hybrid hub/derailleur systems people used to homebrew in the 80s. (That is, a drive train combining a Sturmey-Archer shifting hub with a 10-speed freewheel.) Fascinating proposition.
@classified-cycling: Please update the USB port to USB-C when launching upcoming 12 speed cassettes. Thank you.

I came to this video as I was about to get a Rose bike with the Classified Hub. Today, after 1 month and a few rides, I am completely in love with this transmission. I will have some problems finding a dealer that provides the Classified cassette, but in the meantime, I am enjoying this piece of tech
I was picking up my bike at my local bike shop a day ago. There were a few guys talking with the owner in the parking lot. When I had my bike on my rack, the owner called me over to try something. It was a Moot MTB with a single front chainring. I was told to use a small button on the handle bar next to the left hand break to shift while pedaling. Smooth as silk ... really cool. I made a mental note to look up Classified to learn more. The next day I was researching something else and by coincidence this was in the side bar. I'll bet this is a game changer going forward. As always, Simon Richardson did an excellent job reviewing this technology.
This is something I do not need... and absolutely want
Buy me lunch. We need to talk. ;-)
Itâs slightly concerning when a consumable part, like the cassette, is only available from one small company.
Agree. However - mitigating: 1) it's in steel, so presumably quite durable and 2) it's early on; all new technology is 'one supplier' when introduced. The real test is whether Classified will publish the cassette specifications or whether they will keep them proprietary.
@@dlevi67 Or if they are able to downscale the tech even further so it will accept standard cassettes.
Yea, thankfully though the consumable part is easy to copy as its just metal, so if this tech catches on, all of the big cassette players in asia will produce aftermarket ones.
Hopefully shimano acquires this company and makes it their standard because their front derailleur is god awful. I actually run a sram rival front derailleur on my ultegra bike (with ultegra shifters) because not only is the rival lighter,cheaper and has a free chainkeeper, but there is no trimming so you just set the inner and outer limits and it works perfectly. No fiddling around with certain gears rubbing and others not.
yeah, for now, but it's pretty cool.
@@WARnTEA You are mistaken, It's SRAM that gets the majority of complaints around the internet about the poor shifting of the front derailleur. I have Shimano DA Di2 and I have never dropped a chain so far. When I had SRAM eTap it happened all the time.
Reminds me of when my dad, built an 8 speed cassette onto a sturmey archer 3 speed hub, for his Tandem
That sounds interesting Andy.
Gorgeous tech. Finally no more chainsuck and adjustment issues.
4:14 "I know this...... because i Googled it" made me looooll đđ€Łđ
"You cannot look down between your legs and see if you are in your big or small...." made my day ;-)
and have that reaction "oh my god its shrinking.'
Sturmy archer with a 5 speed Freewheel was around 40 years ago. 3x5 all in the back wheel.
My foldable Brompton has a three speed Sturmey Archer and two now titanium cams still.
SRAM also have a product (www.servicearchive.sram.com/sites/default/files/techdocs/DualDrive_Ins_E_12_02.PDF). This appears to be a more refined version of the idea.
@@bitdiddle1 Bad link.
That's gorgeous and brilliant, I want one yesterday. It's so good I had to check it wasn't April fool.
1950's touring bike set up, Sturmey Archer 3 speed hub with a 3 speed freewheel and triple chain rings.
I also created an online university profile service with pictures in 1999, but somehow my execution was not perfect! It is not always about who is first, but rather who has got it exactly right (and probably a bit of luck), and I think this looks very promising!
@@casperradil Only if there will be second, third and fourth sourcing of cassette parts.
Just posted something similar. Just shows there is nothing new under the sun.
Indeed nothing relly new here. Did not really catch on, why would it do so much better today...
In the year 2090: next copy of the same system. Will be sold as a new invention :D
In my childhood I had a Raleigh Grifter with a Sturmey Archer 3 speed hub and occasionally the gear used to slip and I'd invariably end up on the tarmac! Fortunately there wasn't a lot of traffic around in those days! I loved the bike to bits though.
I heard âmicro-usbâ and died a little inside.
Something this new should be using USB-C!
@@KOME11 - That's still way too techie for me! For adequate durability I wanna see 10mmÂČ copper wires and two bl**dy great wingnuts.
Nothing else will last more than a month. ;-)
@@KOME11 usb C has poor durability
Why? It's never the USB micro receiving bit that dies. It's the plug. They cost as much as a can of coke.
@@TheSorrowedMan and a micro USB doesn't? Give me a break!
I do a lot of miles on a steel frame Hercules Commuter with Sturmey Archer 3 speed hub gears itâs a pre war design and it just works.
As a youth in the 1970s, my dad bought me a huge 'wartime utility' bike, with just one gear. I think it was a Rudge. I rode it everywhere, and the lack of gears didn't bother me.
Exactly. Nothing new under the sun.
I had a maroon Hercules with Sturmey Archer for my school run 50 years ago!
An experience further enhanced by wearing cycling tweeds, a teeth-clenched trusty briar under full steam and stopping for a decent pint.
@@VickersDoorter All before morning assembly in the Great Hall!
Great idea, all it now needs is the ability of sequential shifting as per the SRAM AXS 2x setup and you donât have to work out what gear you need next!
Sturmey Archer CS-RK3 with 3x9 setup gives me 81 gears. Works great on my bike packing/touring setup. It's been around for a while and isn't very expensive
What a madlad. Now imagine with Rohloff + pinion đđđ
@@agunlogisteam does that actually exist? I'd love a rohlhoff hub, but way out of my price range @_@
I have the older Sachs 3 x 7. Probably made by Sturmey Archer, not sure. Bike Friday used to spec them on most of their high end folding tour bikes. They are really durable and foolproof once set up properly.
@@whirving dual drive wasnât SA, but yes - everything new is old.
Was it made before the buyout? I feel like the internals of the older sturmey archers are better quality than this. Although it's been a good hub for me
I didn't want one, until I saw it. Now I definitely need one.
When I was in my teens (40+ years ago) I had a Schwinn with a 3-speed rear hub. All you had to do to change gears was step back slightly on the pedals. Not enough to engage the hub brake, but just a little. I thought it was so very, very cool mechanically. No electricity, no Bluetooth, etc. It was available in the '60's and it was awesome! Here it is again (kind-of), probably a whole lot more complicated. I really liked this shifting method over the alternative of a three-speed shifter on the handlebars. Anyone remember? :) Now I have a Trek Pedelec (Bosch mid-motor), and I'm in the same bicycle heaven again.
That looks amazing Si and you look like one of the Yates twins in those extreme sunnies!
Modern technology but still using Micro USB...
LOL yes!
Yep, lets spec all the new stuff with less popular interfaces.
Why change stuff that works and it will probably only get used half a dozen times before the bike is upgraded anyway.
@@idiachuk USB C has been the de facto standard for years now. I don't even know the last time I saw a micro USB cable around the house.
@@otm646 USB-C spec was released in August of 2014 (IEC standard in 2016), so it's at most 6 years old (and much closer to 3 in reality). Plenty of older hardware still around - not everybody changes everything they own every other year. This said, yes, they definitely should have built in a USB-C port: it's more robust as well as being more recent.
At over 2k it needs some pretty big economies of scale to bring the price down to an acceptable level. Or a kit to fit to other carbon wheels.
Given that some people pay 10-15k for a bike, it doesn't seem that unreasonable sadly
That uphill demo was sick
I guess if there'd be a way to make a version that's controlled through cable tension, we'd probably be able to see more of these for casual riders.
"Smart through-axle" these are the words I would have never expected to hear in my whole life. And I say this as an engineer designing IoT devices :)
That said, this is a great innovation!
I don't even know what IoT is.
I can't wait for smart fingernail clippers!
@@lesflynn4455 *IoT* is the

Really really need more videos like this
What ads, with the benifit of more ads before during and after?
Just thought I'd add a comment after some time has passed since the making of this video. I've just bought a Ridley Fenix Slic with RF50 Classified wheelset and system. Front chainring is a 46 tooth and rear cassette 11 x 34. This suits this 60 year old weekend rider and can say so far am loving it. Expensive of course but aren't all new bike days. Each to their own on what they want but it's a positive recommendation from me.
Funny you should mention Andre Greipel. We were at Rouleur Live yesterday and your erstwhile colleague Matt Stephens interviewed Tom Boonen about Classified but also Greipel who is also an investor/ambassador! Best explanation of the system I've seen so far. đđđ
Imagine the looks of your mates when you climb an epic alpine climb in what seems to be a 50t chainring! :D
đ worth the investment for that alone!
"How? The cadence is high on that big ring? What sorcery is this?"
@@ryanotte6737 just shrug and say youâve been training more lately.
Sur la Plaque!
I run a 50T 1x with an 11-40 in the back so I do this everyday haha
"And I know this, because I googled it." Love these remarks.
I really like this set up and hope to see manufacturers going in this direction. Simplicity.
I am intrigued, Will be looking into this, Thanks Len Halls.
One of the best ideas to appear of late! Bit pricey for many to be honest but lets hope it takes on! Brilliant!
Well it includes a carbon wheel set... If those are any good (I'd hope they are) it's not that bad all things considered.
Old idea (remember Sachs/Sram Dual Drive?), just cobined with wireless operation.
Iâve got absolutely no idea how it works but looks cool!
I love everything about this, and the price will go down eventually so mere mortals can get to enjoy this
As always great video
Congratulations you've rediscovered the typical hub gear.
Btw this concept is something that you can find on bike from the 80s but withput this bluetooth stuff.
I was thinking the same... It certainly looks similar to the old Sturmey Archer hubs from the outside
@@Diesel249 I was thinking the same too, I own a bike that looks like a single speed but has a Sturmey-Archer hubs with two gears. The only thing is that you have to backpedal to switch gear witch can be unsafe sometimes.
For example my early 90s cilo city bike comes with a Sachs Orbit two speed hub gear, on which a 6 speed freewheel is threaded. No front derailleur, good chainline and no dropped chains. Nothing is really new.
@@Diesel249 Sachs had a lot of success with their 3x7 and I think they made a 3x9 also. It was made for a long time.
@@robertunderdunkterwilliger2290 still using a 3x7 on my Moulton , very reliable with updated sram shifters and mech
GCN should invest in a emotorbike for on the go filming. No engine noise droning in the recordings and no petrol fumes for the presenters and more eco friendly. Win win win.
This looks awesome. Would make a nice addition to XC mountain bikes as well. The ratios are way to big on the current 1x setups for the type of riding that I do.
Wow. Brilliant! The future is now. I'm totally sold on this.
I think to be a gamechanger it really has to be available at every price range and easy to fix/replace. Seems complicated and expensive, the beauty of the front deralier is its easy to swap or upgrade, easy to work on, easy to change chainring sizes for more options, don't need to do anything if I change wheelsets etc...
Paid product placement
But that's not how new technology works. You give something like this time and eventually the masses can afford it. Does it work and make sense, that's the question.
@@whatwelearned agreed, however will it ever be cheaper and as usable as what we have now? I guess time will tell.
I can't see the logic it's easy to swap / work on a FD when you now have an alternative that doesn't even need maintenance / swapping / working on? You invent negatives that are simply erased with this solution: why would you need to change chainring sizes or swap wheelsets with a 0.7 front ratio and a 11-32 cassette and disc wheels that brake well in all weather circumstances?
Expensive, yes, but within the (crazy) current market standards where each top end disc bike seems to cost close to 10 grant. Complicated? I don't know what is complicated about having no FD, and having close to no maintenance.
@@andylock3247 If it's currently 2k+ then it might be a while ha
i'm ahead - already fitted my sturmey archer 3 speed hub. Got rid of two chain rings.
can you mount a regular 10 or 11 speed cassette on it?
Finally a new useful tech! Fantastic, love it!!!
Very cool, I hope it takes off and the company has great success.
Modern development of an old idea... i like itđ

Sounded like a skipping chain lol
@@derekmcmaster8191 They should use electric motorbikes
Excellent review. You guys do a super job at reviewing products. Thank you. As a recreational road biker, I love the idea of taking the front derailleur completely out of the equation. Aside from m cost, not sure why this isn't on every rec road bike - or at least an option.
For starters: because the hub alone costs more than the vast majority of complete bikes out there?
This seems to have a lot going for it. It's something that may very well appear on my dream Ti bike build in 2023, after the early adopters have paid for the R&D! I love the aesthetics of a 1x setup, and this is even better because it doesn't require a pie-plate cassette.
Saying that, the cost of the cassettes could be a concern for me. Hopefully if this catches on the cost won't be too prohibitive.
That set up costs more than my entire bike.. *sigh*
Yes, twice as much.
It said it comes whit carbon wheels, some carbon wheel alone cost that.
@@dunigan3320 then some carbon wheels cost more than my entire bike.
@@-paulmp yes
The usual comment for all new bike tech.
Will definitely catch on. However, at that price I won't be replacing my 3 (S-A) x 8 hybrid setup just yet... LOL
Wow, I really want this now. Would be so awesome on my 1x gravel setup. Currently running a 9-46 e13 cassette to get the range I want for my 11 speed derailleur. Would love to have the closer gear ratios I have on my road bike AND get the big spread AND not have a front derailleur. Cool stuff. Thanks for the video.
Looks very promising. My main concern (apart from overall price) would be the proprietary nature of the cassette.
Brilliant! When will the MTB version be available?
As a Brompton 6 speed rider, that has hub gear and rear derailleur, just glad that big wheeled bikes have caught up! ;-)
I love this though. Would 100% convert me to 1x on big wheeled bike. If it were only a little cheaper!
Give it a few years and it'll probably be the go mate.
I like the concept of the hub very much! Would give it a try or - even better - a go!
The Ridley Kanzo Fast is just gorgeous
This linked with syncro shift would be awesome!
Yeah! At best it could be connected to the Di2 bus and also draw power from there.
It would be awesome if sram adapted this under AXS - you'd have 1 shifter and it could smart shift through the range
Given they already have something similar with the dual drive hub, this could be a possibility.
Sram all the way
@@theRealDavidn Except for the poor quality when compared to the top two (Shimano & Campy) and operational issues.
@@ChromeLuxx agreed
@@ChromeLuxx I might be biased - ridding sram for 3 years now, 0 issues
It remembers me of when Truvativ came out with the Hammerschmidt, on what I believe was a first attempt to bring a one by setup to the market. I had one on my Mondraker Prayer, it was incredible to ride, no electronics though and heavy as F#, but it was built to last !
Great Vid - very interesting tech, bet we start to see this on lots more bikes
They used to laugh at out internal speed hubs, but look at them now
Ollie needs this! And an e-motor in the hub wouldn't hurt his performance either.
I would love this hub for my cyclocross/gravel bike! 22 gears on a one-by set-up, awesome!
I already removed my front derailleur and modified my chain ring to a single speed with a 48T and kept my rear 11spd 11-32. I love my set up. Been fine for 2 yrs like this.
Ooooh Si in a video!!! And getting his hands on some cool Tech!!! Wonder what the bike is under that paint job.... !!! Looks and sounds class Iâd buy it!!
rildey noah
I think he said itâs a Ridley kanzo fast
Think Si said it was a Ridley again
I haven't used a front derailleur for a few years now, but I don't need the widest range of gears. 1-by works well for me.
Like always say let wait and see more time and the competition will bring it to perfection
Where is this segment filmed? Beautiful locations and cool new tech.
Combine it with a front derailleur for a 4x setup.
Genius
Isn't better to just add another gear on the hub? Kinda complicate things more isn't it. So essentially it's a 3x or even a 4x if it's possible.
@@DrunkieCat i guess if you play around with the ratios right you can get an extremely wide range of gears
@@user-ko5kk9ud8k Exactly, that's what I was thinking. You don't need a wide range casette or even a 13 speed. Get an 8 speed and you can easily achieve the same thing or probably better. With syncroshift you can easily make it a thing, let the tech do the calculation.
Using 3 shifters?
I took about 60 seconds to reach the "shut up and take my money" stage đ
Save your money and buy a used Sachs Orbit or Sram-Sachs Dual-Drive hub. This idea is over 30 years old and was in production until the mid 2000s when the latest iteration with 3x9 gears was taken off the market.
"If you ask the price you cannot afford it, sir".
Wow, impressive!! What an invention!
Modern improvement on what I used back in the 60sđ I had a Sturmey Archer 3sp hub mated with 3sp rear derailleur. Proved to be very reliable and effective system (no duplicate ratios).
OMG that's what I thought of when I saw this video, it seems like a great idea.
Put it on disc wheel for a cool TT setup
SI BACK AT THE TECH CHANNEL
Really loving the Top Gear vibe on this video.
Often wondered about fitting a cassette to a sturmey-archer hub when I was a kid. Shouldâve tried it :)
Genius! What a brilliant system. Canât see any downside other than the cost and the proprietary cassette requirements. Iâm sure this will change over time though as itâs adopted by more bike manufacturers Another great video as always GCN đ
Planetaries have been around for a very long time, the reason they haven't been used in modern cycling applications is because the mechanical drag is substantially higher.
I guarantee you this system comes at a weight and efficiency detriment.
@@otm646 difference is that this is a two speed planetary gear system which massively reduces the negative aspects you mentioned.
@@otm646 Which is not what they (Classified) say. Obviously. Not that any of this is hard to measure in a decent lab...
Yeah, and about a 10% loss in efficiency versus a conventional 2X set up. Brilliant. LOL
@@hogdog567 Wrong. This system will likely run at about 10% less efficiency that a classic 2X set up just due to the internalized hub gears. Add in more inefficiency due to the extreme chain angles the chain is at whenever it is near the lower or upper gears of the rear cassette in this 1X set up and you are talking about a large loss of power. There is a reason why no pros or serious amateurs ride internalized gear rear hubs.
Oldschool technic in new packeging!
I had one of those, maybe 1982 I got a bike equipped with "Sachs Commander/Orbit" group. No wireless shifting and only 6 speed cassette bit still, same idea. Was my pride and joy and still is. I ride the same bike to this day every day, obviously replaced parts over time including the frame, by now there is not a washer left from when I was 15. Still the same bike though, never bought a new one since. Oh and when the frame broke the first time it was time to get a proper front derailleur.
That's the coolest drivetrain technology I've seen come along since STI.
A belt drive "single speed" would be pretty cool!
I'm thinking put this in an electric, with another planetary gear in the BB, add wireless charging via magnets, and you can lose all the cables and run everything off the battery.
Si and Lloydy have the most refined voice deliveries on GCN. There is a reason I like to listen to English spoken by those from England... it just sounds as it was intended to sound. Cheers Si!
Superb innovation. It sounds like they have nailed it. Possibly most economical on a new bike. Great innovation - and the icing on the cake is displaying your gears on your smartphone!
This is awesome, Iâm definitely looking in to it, hopefully my favorite bike dealer is an authorize dealer
For people who donât want 1x, this would also open up great opportunities to retrofit 1x specific frames such as the 3T Strada (I know the Due exists) or the Allied Able.
I am riding 3T Strada 1x and 50T 11-36 setup is not versatile enough. This is definitely a wonderful solution in this regard!
Yeah this feels perfect for the Able
I'm surprised its not been done before. It's actually nothing new, Brompton been doing it for decades. Just needed to adapt to a road hub
It's been done plenty before. It used to be common with tourers - use a triple chainring and combine with a Sturmey -Archer 3 speed hub.
The item you just saw was automatically ADDED to your wish list ...! ;-)
In the 1990s I had a friend who was touring a lot on a shoe-string budget. His bike was a steel frame with a Sachs gear system with a six-speed cassette and a cable-oprated rear hub Hi/Lo function. Very reliable, but it negated the quickrelease. However, after he chose to tour with a quite heavy home-built cart, I retrofitted the bike with two chain rings and a front derailleur, giving him 12 extra gears. He toured most of Poland at least once on that bike.
As smart, efficient and durable this Classified hub gear appears to be, I'm so old-school that I find that a bicycle that cannot operate without electricity isn't a *genuine* bicycle. For me, it's a no-no to electric shifters and BT hubs. I want steel cables, even though they are slower and less precise.
I don't mind the experimentation, though, because it has brought many benefits to cycling, even for me, like clipless pedals and ceramic rims (I know, my Open Pro Ceramics are laterally soft as melting ice cream, but they brake like nothing else in wet weather).
