There was a patent for a SRAM direct mount derailleur one year (2018) before UDH got announced - google - Patent Patrol: Direct thru-axle mounted, hydraulically damped SRAM rear derailleurs - so everyone in the industry knew what UDH was for, and where SRAM were going with it, when it got anounced in 2019

Here's nothing really standardized except the hanger. I'm afraid unless they make their mounting system etc. available just as free or for a very reasonable license fee, and allow some leeway in the implementation of other solutions with the same goals by other brands regarding the protection of their patents, there'll be a lot more incompatibilities coming from this. We'll have to wait and see, as always. But I highly doubt they did you any kind of favor as a mechanic.

On another note, I've just fitted XPLR AXS to my road/gravel bike and the shifting is just brilliant. Easily the best shifting setup I've ever used (and I have various 11/12/Di2 setups). Sram are nailing it at the moment.

Now I feel old. I do remember bikes not having replaceable hangers, I even owned an aluminium frame with a fixed hanger. I guess work hardening didn't mean anything to them. This looks like a brilliant idea from SRAM, once it filters down to the more affordable groupsets it'll probably start a revolution. Let's hope that Shimano patent for an internal gearbox turns out to be workable.

That was a good job of pointing out the major changes, benefits and behaviour of the system. Everything has both compromises and benefits. You just have to choose what's important to you. I look forward to getting some version of this down the road. Have a great day and go ride.

Excellent video. Better explanation than any of the other videos I've seen on Sram Transmission thus far. Thanks!

I really love what this drivetrain brings. Never having to adjust the derailleur alignment and shifting under load is a dream. The initial cost is really high, as expected for new tech. It seemed worth it though and I was SO close to buying it.. until I saw the price of the consumables. There's no way I'm paying those prices for the chains and cassettes every year, maybe twice a year for the chains. That's a crazy subscription price! Definitely looking forward to seeing what comes next with direct mount derailleurs. Hopefully a more realistic running cost.

I bought a new bike in May with an XO Transmission and it has been flawless. It's very quiet and has held up to all the bike parks so far. I only dumped it on the derailleur once at the park and had no issues, just like all the videos show. I charged the derailleur battery once in two months also. There's no issue with taking the wheel off and retighten the axel or anything finicky like some comments are worried about. Once the price comes down and more people use it, I can't see anyone disliking it.

Great job. Clear explanation and a very fair treatment of the subject, withholding nothing. Positives, negatives, trade-offs, what is gained, what could be lost. I'll be watching for more.

I have pretty good insights into the pro world of enduro mountain biking, although I'm just a spectator myself, like the majority of cyclists. However, the current opinion of pro mountain bikers about the new Sram Transmission is that it is not durable enough to be used in World Cup races. Sram has removed the derailleur hanger, but that comes at the expense of a less rigid derailleur cage. The impact tests you see always go to the stress on the attachment to the frame, not the cage of the rear derailleur itself! Since the introduction of Transmission, it seems many pro riders in EDR have had failures, with some teams even sticking with the "old" AXS groupsets altogether. What does that say? Transmission is so far mainly a marketing masterpiece.

So the standardization around UDH or UDH-Direct Mount configurations is a great thing for the industry. I hope gravel kit starts going that way too. BUT, I am concerned about the proprietariness of the full Transmission system. Time will tell if the industry can normalize on the UDH/UDH-DM setup.

Solid explanation. This makes sense for pros and competitors. I'm all for tech, but the dealbreaker for me is the rechargeable battery. What if you forgot to charge and you lost battery near the end of your day? If you're a pro, you have someone to ensure you have extra batteries and it's always charged. Your typical weekend rider? Not so much. I've never had any major issues with mechanical and plan on staying with it for the foreseeable future.

I would thoroughly enjoy a cable actuated version of this. Personally, I don't really care about the shifting under load part, but I am a big fan of not having to adjust my derailleur, or worry about it falling out of alignment when I smash it into something. That being said though I have never, and probably will never like wireless things in general, even not relating to biking, its just one more thing to remember to charge or else it fails.

And as much as I agree they planted a Trojan horse, I think what it also did, it gave industry a time to prep for the next bigger step. Let’s face it - derailleur hangers were around since very first mountain bikes, steering away from them must be considered a big step!

Thanks for covering this topic! I actually have never heard of this new system and I admit that I'll be kinda late coming in contact with this, because for the past 10 years, I'm working at a Charity organisation "THE CROSSROADS FOUNDATION" IN HK, that receives all used, donated, OLD bikes, in a working (or not) condition and overhaul them for free (I'm retired) so that they can send the overhauled ones to 3rd world countries (mostly in Africa, Vietnam, Phillipines and India) to the under-privileged and Local Doctors and Missionaries, some of still walk from villages to school or work. Like I say, It'll be some time working on OLD DERAILLEURS till I come across this, BUT, thanks again for this NEWS (to me)!

But I don't know how SRAM could make a system like this easy to repair. By necessity, the electronics are extremely compact to ensure the footprint is small enough. It's not like bike techs are going to crack open the case and go at it with their soldering irons. I work on my own bike as much as possible. I'm pretty good at setting limit screws and indexing the gears so the Eagle T does not appeal that much to me at this time even though I think it's pretty cool. But I can't say I'm concerned about losing right-to-repair privileges. And just think about it. If SRAM starts trying to bilk customers by forcing them into controlled service and repair channels, riders are going to revolt. I'm sure they will do all they can to maintain goodwill with the community. At least for now. I mean, Elon Musk could purchase SRAM and then I'd be worried.

⁠true, but on the downside it’s heavier than a derailleur drivetrain, and has much higher internal friction losses…. all of the internal gears in the pinion gearbox are constantly meshed, even though only one pair is driving at any given time, like an automobile transmission…. the big benefit of chains and derailleurs is that they’re very efficient at transmitting power, and they’re lightweight…. and can put up with a lot of mistreatment, poor maintenance and misalignment and keep on working…

So happy i watched your video. All the other marketing based videos haven't made it clear about the udh interface which leaves people thinking they wont be able to upgrade... now they know there is a good chance they can!!

Great review and thanks for the pros and cons. Lets wait for shimano and other brands to follow the trend. And to think the debate about changing wheel sizes from 26" to 27.5" to 29" wasn't that long ago.

SRAM is full of it that 50% if shifting problems are related to derailleur alignment and you don't need a special tool to get them back into alignment. Most people don't even know which limiter does what or what a tension screw is. Ignorance, poor chain maintenance, and reckless shifting are the reason for most shifting issues. Basically they built a an expensive component for people who don't want to do bike maintenance. I have smashed 1 rear derailleur beyond repair in 30 years of riding mainly ungroomed hiking trails.

There are already lots of broken ones out there. When you crash, *something* has to break no matter how cool it looks to stand on it in photo ops. A $20 hanger is better than a $500 deraileur and even a through axle which will need a shop to remove cleanly. The true failure point is whether SRAM can provide cheap and easy to get replacement parts and let's be real, they actively try to prevent people from getting repair parts for their products, have zero availability of most parts, and price things in some regions like they don't even want any sales. I like new ideas and net tech, but this is a bad solution to a made up problem and going to be be discontinued with no replacement parts within 5 years.

To add to this, when you write off a traditional derailleur it usually just takes the hanger with it as that's what the hanger is for. When this thing breaks it very well can (and probably will) take the axle and frame with it. Axles are not invincible, hell they're not even absurdly strong and when they break they can take the frame with it. Just ask Rocky Mountain what happened with the Slayer they gave to Pinkbike 🤣Not having that barrier between the derailleur and frame is going to prove to be an issue when you hit the thing hard enough to shear it. And that's not an if, it's a WHEN. I don't care how much your marketing team says that you can stand on it and hit it with a hammer, that thing will shear eventually.

@@englishwithtimusa hype? ha. no. you need to remember that these groups are at the high end niche, a fraction of a percent of the market for "performance" mountain bikes. Absolutely no one will follow and because sram is only popular at the top end and has low to no share on bike under a few thousand bucks, this is going to fade away... And that is if the product was GOOD, which it is not. Shimano, who does control the broader market tried a new hanger spec a while back... abandoned as of 12 speed cause absolutely no one was interested. But at least that is just a hanger. And wolf tooth I don't see making upper derailleur assemblies that hold the battery pack etc. That is sram's job. Right NOW, the only parts available are cage assemblies for $140-$200 usd - which is flat out absurd. Transmission is a disposable $500 derailleur built at a time where buyers are fighting that concept and laws are being implemented to actually stop product designs like this. There is a pattern to SRAM's business, and this fits right in. Flashy, proprietary, full of hype but not particularly well engineered, and abandoned in a short time. They are the Sony of cycling.

I think shimano won't drastically change anything. They have the advantage of being able to shift a lot of gears very quickly which is super useful in undulating terrain, and shifting under load is really good too. Still very curious as to what they'll bring to the table with their next gen XT groupset.

Yep, the worst thing about my GX Eagle is the ability to only shift down a single gear per click where my old XT M8000, 3 gears from 1 press. Anyone who remembers the transition from regular and uniglide cassettes to Hyperglide remembers how much better shifting under power became. It will be interesting to see wear profiles of Shimano vs SRAM with power shifting vs soft peddle shifting (well softer after uniglide). Power shifting anything with a chain, ramps or timed shifting is going to wear it quickly.

I haven’t tested the new Stam group set to see how this shift under pressure works, but on a XC race I prefer always a fast gear shifting as my XT provides. My Super Caliber gen1 is UDH and I’m studying if this changes bring me some benefits… 🤔

Love the SRAM T-Type stuff here. My boss at my shop owns it on his E-Bike, and he absolutely smashed a Cage on his XO, completely bent. Nice part of this new stuff, is you can just throw a new cage on. Didn't fix any of his shifting issues, and he needed a while derailuer again.

Been riding the new Sram XX SL transmission for about a month now. Absolutely love it!!

I'd love to see a derailleur that just mounts to the thru axle like this with none of the other frills, as although it all looks amazing, electric and wireless drive trains are definitely out of my budget for now.

Really nice breakdown / walkthrough, I valued the video. Cheers.

Tbh, this isn't a big deal really. It's too expensive for many and just an improvement on what we already have. The derailleur is still vulnerable to rock garden damage and it's still alot of weight at the wheel where we don't want it. We need more efficient sealed transmissions like the Pinion gearbox's. The weight is centralised and sprung. Maintenance is minimal too. But, that's probably not as profitable as mechs & cassettes for Sram & Shimano so we'll probably never see one from them anytime soon.

True. I tested the brand new Pinion e-motor (with 12 speed integrated gearbox). That thing shifts so fast (way faster than SRAM wireless) and is maintenance free with a belt drive. Only a oil change every 10 000 km. Only thing is, it is more suitable at the moment to the ebikes (because of the weight). But we'll see in the future.

Like Seth said in the vid, the thru axle needs to be tightened to a certain torque spec. What happens when you need to take the wheel out on the trail. You won't have a torque wrench with you. Will the shifting be that much worse if the axle is not tightened to spec?

Just like everything that’s analog on your bike it’ll get you home perfectly fine. The reason you took the wheel off is probably to fix a flat. Do you have a method to get the psi exactly right? No, but it’ll be close, it’ll get you home, and you can torque or fix the PSI later

You can align your drailleur hanger with an old quick release front wheel. Does not matter if MTB / ATB / or road. Unscrew your derailleur, screw in your wheelaxle ( jep, it will fit ) and align your derailleur hanger with the wheel.. 😎

I love your videos. They're entreating and easy for knuckleheads like me to understand!!

I think SRAM did a really impressive move with this product. I personally will never consider electric shifting though. For me a bike had to be 100% self-sufficient. I want it to be always ready. Imagine you can't ride your bike because you forgot to charge the shifter. That's why I also have dynamo lights.

This is DEFINITELY false. During the pandemic, while Shimano's products disappeared from the market while they were ramping up for 12sp Dura Ace and Ultegra, SRAM was busy bringing us all Rival and GX AXS. Then when Shimano brings out 12 speed 105, SRAM brought us Apex AXS. SRAM has long been eating Shimano's food on the lower end side of the market. I think they're genuinely trying to bring about something that will improve mountain biking. Because L-TWOO and Sensah and Microshift and Box have been forcing Shimano and SRAM to be competitive with the lower end...

@jeskli11

Shimano is much more focused on the performance road bike market, where it massively dominates over Sram (well, not speaking of powermeter accuracy… but in terms of efficiency, front derailleur shifting speed and number of teams using Di2 over AXS). I have ridden a few different levels of mechanical Shimano as well as Sram Eagle groupsets, currently I have Shimano XTR and it's leagues ahead of anything else I've tried and if Shimano wants to keep the MTB drivetrains mechanical, there's little room for improvement. That puts Shimano in a difficult situation, because the only way to improve its top-end MTB drivetrains would be to switch to electronic and wireless, or direct mount or both, all of these variants would be (I guss) hard to achieve without conflicting with Sram's patents. Sram on the other hand doesn't care about entry level stuff, so that's where Shimano gets money in the MTB department from and maybe doesn't really need to focus on renewing it's top-end components, since they're still more than capable of winning World Cup level races.

Such a good fun and informative video and an amazing looking product. Also, it really can’t hurt to have to own a torque wrench. Torque specs are there for a reason.

We need more standards like UDH!

I love axs. I wish all my bikes were wireless because cables are always changing and requiring adjustment. The weight difference is negligible.

So many great reasons to stick with the pre-transmission drive train! Thanks for the explanation!

So love this and am looking forward to the day it is affordable to me and mine. I think SRAM are geniuses for come up with the long play. It is well past the time where we have hundreds of different hangers. This should have been standardized a long time ago!

The only reason I don't like wireless is on principle. A bike should work properly without batteries of any kind. There is no reason why a system like this couldn't be made battery free despite requiring electronics.

After having a couple of emtbs in the stable the past few years I have to say that this new group set is evolutionary. I’ve been running the new XO on my Levo lately and it is light years ahead of the old stuff. Time will tell how it holds up, but I’m tracking mileage now. After blowing through chains and cassettes at an alarming rate, this is worth it for an Ebike at least. Shimano is working on a link glide drivetrain that can shift without pedaling on e-bikes by using the motor to spin the chainring. That will be game changing. If you can press the shift button but keep your pedals level and the bike shifts, it could really open up some new possibilities for riding janky lines

Oh I already see lots of lost battery/port caps on the trails... that's what's gonna change... oh, and also it will become harder and harder to get a off-shelf bike without those pesky contraptions... yeah, i know it's just my problem, but still I prefer a fully mechanical gear, the simplest the better, so there's less thing to break and easier to fix out in the wild... granted, i'm not into competitive biking, just a bike touring guy, which brings everything and a kitchen sink along, so it might not make a big difference in the long run. most things rarely break if build well... still... another gizmo to keep charged! they could fit a dynamo in jokey wheels 🙃🙃

As an engineer, I have serious concerns about direct mount as a concept. Sram can talk for as long as they want about how strong they made it, but in an impact, *something* has to give. That's just physics. With no replaceable hanger, the options are: a) the deuralleur body, b) the rear triangle of the frame, or c) the wheel hub by way of the thru axle. I'm sorry, but I'd rather replace a 5 dollar part. I'm not going to say there are no advantages to direct mount, but I think Sram is being extremely cavalier about the system's risks for the sake of flashy marketing and forcing a proprietary standard that they control into the industry.
