SRAM to Introduce a $15 Universal Derailleur Hanger - Eurobike 2019

Sep 6, 2019

SRAM Universal Derailleur Hanger


There are a bunch of places on a bike where I suspect that we'd all love to see some uniformity applied. Seatposts, hubs, and bottom bracket dimensions, and of course down at the derailleur hanger. We'll have to keep waiting on the first three, but SRAM is moving ahead with their $15 USD Universal Derailleur Hanger to tackle the latter. Not only is it just $15, but it's also open-source; there are no licensing fees.

Why should SRAM do this if bike companies already use their own hangers? That's actually part of the problem, with some brands deciding to use dozens (or more) of different hanger designs over the past few years. Do you need the hanger from 2016 or 2017? There's a good chance that they're different, so you better know the answer. Maybe just before you're about to leave on a road trip? That'll be a two-month wait. An absolute nightmare.

Conceptually, having a single hanger that's used across different brands and different bikes makes sense, even if there are countless variations out there already. A case of better late than never, you might say, just as long as enough brands get on board.

See that ramped fin that extends above the hanger? It's there to guide the chain back onto the cassette if it happens to get bounced off one of the smaller cogs.


In a way, it makes sense that companies responsible for drivetrains should also be responsible for the derailleur hanger. SRAM wants consistency because it means fewer variables and fewer opportunities for things to go south; if they can control the hanger's geometry, they'll know precisely where the derailleur sits in relation to the cassette. Fewer variables, more consistency, and likely better shift quality. Think of the possibilities with electronic shifting, too...

Word is that the hanger is designed to rotate backwards if the derailleur is smashed into something. It doesn't return on its own - you'll have to dismount and push it back into place - but I suspect that it takes an uncommonly hard hit to make it move. The UDH works with all current derailleurs. And yes, current derailleurs also pivot backwards themselves, but in the future they might not need to if that functionality can be built into the hanger.

There's also what looks like a ramped fin that extends above the hanger. It's intended to help guide the chain back onto the cassette if it's bounced off one of the smaller cogs towards the frame. This should put an end to getting the chain jammed between the cassette and the frame, a rare but annoying occurrence.

The UDH is designed to rotate backwards if impacted hard, hopefully saving both it and the derailleur in a worst-case scenario.

The 2020 Trek Fuel EX that I reviewed last month had the UDH.

No, they're not forcing frame manufacturers to jump on board with a proprietary system; it doesn't require a different derailleur - anything current will work just fine, including those from Shimano. There are already bikes in the wild using the UDH, including the 2020 Trek Fuel EX that I reviewed not that long ago, but expect to see more in the near future.

Does it make sense? Should drivetrain companies also be responsible for derailleur hangers? Or are you doing just fine with the way things are?

 Nah, this seems way too altruistic for SRAM. This is probably some devious plan to make all frames incompatible with Shimano in the future iterations of this standard.

 Excellent! Now only make one that is compatible with Shimano direct mount!

 @Konyp: Just wait for the next iteration, UDH-Lite which saves 5gram but is incompatible with all frames from before 2022.....

 @WAKIdesigns: translation for all the joeys:
Shimano created their Shadow Derailleur direct mount rear derailleur universal standard in 2012 to address these concerns of frame manufacturing inaccuracies as well as locating the derailleur further back for increased performance and ease of wheel removal.

 @sriracha: they just shot themselves in the foot a bit. Most of my shimano shadow rear mechs failed due to the "shadow link" bending. That direct munt was supposed to eliminate. replacements ae hard to find and their cost is ridiculous. like 25$ or something.

 I'd say leave the details of frame design to the producers, don't need a "standard" constraining their design process, and the cost of a hanger doesn't really break the bank. The manufacturer of my frame usually has it out to me in a couple of days. I never actually broke one either, I just asked them for a spare just in case. Oh, and their hanger works across the multiple frames and models.

 Yeah I don't worry about running the derailleur into things as my SRAM brakes are constantly seized on to the rotor so i am forced to ride slow. Why don't they spend some time on a universal disc brake that works longer than 3 months?
  • 12 1
 @McNubbin: It's not out of the kindness of their heart. It's for $15. What they are doing is offering a product at a very competitive price to gain an advantage in that market. They get our cash and business. We get a good product we need at a really good price. It's win-win. It's not that everyone is naive. You just seem to have trust issues. Haha!

 @TheR: Because this is something that literally no one asked for. Is paying $20-25 for hanger from you manufacturer really that much of a hardship? You also should have extras to begin with. Plus, I’d rather pay $5 extra and buy from my bike maker (who’s quality I KNOW is top-notch), vs. SRAM.

 @McNubbin: ever try ordering one. My local shop is Specialized, pretty sure they won't have a hanger for my bikes that aren't that brand (all but 1). Sure $15 is steep, but if it became something as easy as a tubeless valve to buy, I'm all for it.

 @McNubbin: I'm not sure what your point is. Your original comment was we were all naive and thought some company was doing this out of the kindness of their heart, with nothing in it for them. My point was, no, I'm well aware they are not doing this out of the kindness of their heart. I know they are doing it to make a profit. So what? They get my money and my business, and I get a part I need/want.

As for this being something no one asked for, I beg to differ. Last spring I broke the derailleur hanger on my boutique-brand bike in Moab. Moab is kind of an isolated town and does not have a shop that carries my brand, so there was no hanger to be had. This little part certainly would have solved my problem in a matter of minutes for $15. Instead, I had to rent a bike for $225 for the weekend, or my little vacation would have been ruined.

And yes, I should have had an extra hanger. About that -- I know I'm hard on this particular part, so I ordered one from my bike manufacturer a week before I left on my trip. If they had shipped it on the day I ordered it, I would have had it on time. But since their customer service apparently isn't what it used to be, it shipped four days (two business days) later. That last part is on them and their customer service for sure, but stuff like this happens. And also, let's face it, this isn't a part many people think about until they need it. I would gladly pay $15 (which, by the way is $20 more than the manufacturer's hanger) for such an occasion.

 @cmrn: the issue is, who will follow auit. DUB has also been a great idea on paper, the trouble is it’s just another axle diameter, only difference being GXP is phased out. It simply replaced GXP that’s it. So it’s great for SRAM and SRAM only as it simplifies their production, but everyone else is now dealing with DUB and remnants of GXP for many years to come. So yeah, the only good thing here is that all Trek bikes will have the same hanger. Trek Factory stores will have 1% easier life in 5 years

 @filwhip: a good barometer of the extent of vested interest then. I mean the list of proofs is f'ing endless, so don't think i'm too far off base (DUB, FFS, marketing that the spindle diameter was somehow devised out of anything but someone's arse).

it's for sure a great idea, but my guess is it will fare as well or last as long as any other standard in MTB does, assuming it takes off (which I don't think it will).

i think frame makers will be the big limitation (their willingness to play ball). that was always the issue with BB standards when carbon started getting popular, everyone on road bikes had to go wider, or do this and that to optimise the frame, so we all had to have a different BB. Trek's no different sticking with a stupid variation on press fit for years, then adopting but maligning the T47 standard.
  • 8 0
 I can think of 28.99 reasons to suspect you may be right.
  • 9 1
 This from the company that loves to make "standards" hardly anyone else adopts. Anyone remember ISIS bottom brackets... great open source idea but hardly any manufacturer put the R&D into the bearings as shimano had done with their earlier Octalink bottom brackets so eventually it became a largely failed idea. Having ISIS wasn't good enough for SRAM, they had to have their truvativ division come up with powerspline which wasn't used by anyone else. Later when Shimano moved to external bottom brackets at the higher end, lots of other brands moved to copy/license it...RaceFace, FSA, Hope, Chris King, dozens of china/taiwan bike brands & manufacturers and all are compatible to one another thanks to all the cranksets using a 24mm diameter axle.... SRAM gave us GXP with the 24/22mm axle and incompatibility to everyone else. The reason for frame manufacturers to have different hanger standards for their frames has to do with how each frame is designed. There's one particular hanger used on open dropout aluminum frames by dozens of brands and hundreds of models now over the past twenty years for example.

 PB comments will hate on Sram no matter what they do - they could make the best drivetrains on earth, the most powerful while modulated brakes, make all their products backwards compatible and get rid of the issues of gearboxes, but PB will still conclude that Sram is the devil.

 @wildedge586: Yes, they give OEMs discounts on bulk, since they make a lot of stuff and that makes them bad because? I haven't had any issues with my slash 8 (RS deluxe, which I'm quite impressed by, yari fork which aside from the MoCo damper is really nice too, the GX eagle just works and the guide r's while not outstanding are enough for me) and a lot of pros have ridden on sram for years without switching. There will be some faulty products, but that's because they are equipped on so many bikes. Just about every brand has had some issues with their products, which are highlighted in PB comments by people with faulty products that come to vent their frustration. There's just more people with faulty sram stuff since there's a lot more people with sram stuff in the first place. This means that there's a ton of riders running sram that you don't hear about since they spend time riding instead of complaining online about their bike.

 Some may be shaking their heads but having 1001 hanger specs versus 1000 hanger specs is really not going to rock the cart that much. What will is for the individual bike makers and boutique manufacturers potentially loosing a guaranteed 2000% markup on a small piece of aluminum they charge 40 to 50 bucks for.

 Sick! Just slap this on with your shoddy Nx/Gx derailleur (with half of them being warrantied for their faulty clutch), and your garbage E 13 nevershiftright cassette, and pass the rage on to your local bike mechanic: (unfortunately) me. Then you'll have one hell of a compromise drivetrain that works about 60% as well as a legit group (which is paired with a manufacturer derailleur hanger that is absurdly easy to obtain from your frame manufacturer if you plan ahead in the slightest way).

 At first glance it looked like a Trek hanger... Yep. If it works in ABP frames it'll be sort of excessively wide for a bike with narrow dropouts, like say, my carbon road frame. I guess you could unnecessarily widen all driveside dropouts but XC racers hate extra carbon. To be fair we have a Wheels Manufacturing dropout chart at our shop and it probably has 100 different hangers. Even Trek has hangers that are NEARLY IDENTICAL except one uses a M2 screw and the other uses a M3 screw. Look in the drawer think you have the part, realize some dumb dumb put M3s in the M2 slot. Then there's my Chromag, which has a hanger that is made in house, so I have to have one mailed to me from across North America. I buy two at a time.

 Modern 12 speed drivetrains need a very precise alignment. This is a way to address that.

Also, this looks a lot like current Yeti hangers, which are really well designed. No tiny, crappy little bolts-easy to field replace in a pinch.

And.....open sourcing standards like this is the way forward. Hopefully the other S brand plays along (they have on some SRAM stuff) and the trivial but massively frustrating proliferation of (often poorly designed) derailleur hangers will come to an end.

  • 1 0
 I can design a bike part and call my part a new "standard" too, but that doesn't mean everyone else in the industry is gonna get on board and start using it. Absent something like creating a compatibility problem or refusing to sell drivetrains to OEMs who don't use their hanger I don't see how SRAM is gonna make this "universal" or "standard" and twist OEM arms into using this hanger exclusively. There are too many imaginative people in this industry and too many users who like to try new things for this hanger to just take over the market. If it did, that would be great, but I just don't see it happening.

 I drove the SRAM race support rig and wrenched on bikes at the NORBA races in the 90s. Those were the pioneer days of MTB frame design - especially with the advent of full suspension. SRAM's then new ESP derailleur struggled with derailleur hangers that were too long and left a large length of chain between the upper derailleur pulley wheel and the cassette.

I imagine that with the new 12 spd (and 13spd) shifting systems the tolerances are becoming touchy again. Developing a standard derailleur hanger will help component manufacturers/engineers design around a fixed tolerance.
  • 2 1
 I think most of you are missing the higher picture. The standard mount for a derailleur is quite antiquated. Imagine if companies world wide got on board with a new hanger design. This opens opportunities to improve the derailleur system. Currently there are limitations to this. B tension plates snapping, the flopping back and forth of the whole derailleur on the B tension. TRP has the hall lock which essentially locks the derailleur forward. I see this as the next step in bettering the drivetrain. This is definitely not geared towards unifying the industry standard in order to bring ease to the consumer. Proprietary is great for big companies like SRAM, it helps them keep market shares, and forces other companies to up their game. I for one am on board, but not for simplicity, or ease... But for innovation and improvement.

 It would be amazing to have all of my bikes and my kids' bikes using the same derailleur hangers so I don't have to keep 6 different hangers in the house. I've already simplified the brake setups to Shimano on the kids' bikes so I don't have to do much in the way of regular maintenance and Sram on mine until I get around to buying a set of TRPs. I love the feel of my guide RSCs but I hate how frequently I have to bleed them compared to the Shimano stuff on the kids' bikes.

 The problem is this looks flimsy and flexy compared to the hanger on my Remedy. I'd rather have a hanger that is stiff and straight. Have you ever seen Sram brake rotors?: Thin, flexy, and bent when brand new.

 Thats is the whole point of derailuer hangers. They bend to save your derailuer from breaking and are cheap to replace (if you can find one for your bike). This solves the availability problem.

 Get people to adopt your "open" standard for hangers, move to direct mount based mechs on it which your major competitor Shimano can't do (the standard is open for making frame that accept the hanger, but I bet it's not open for building a direct mount mech that fits the same holes).

It's the same as the hub standards, anyone can make wheels to fit it, but you're not supposed to make cassettes.

 Now if only they could decide between 30.9mm and 31.6mm seat post diameter. I'm sure that 0.7mm is really making all the difference...

 Congrats to SRAM for opening up and making a universal standard! Best news I've heard in a long time.
Is it too early to ask for a standard hub width and wheel size? Smile

 "they're not forcing frame manufacturers to jump on board with a proprietary system"

I mean it's also not actually proprietary.. it's open and royalty free, ie the opposite

 @mikelevy: maybe as a down-country evangelist the unholy gearbox spreads fear in your heart; personally, I’m an enduro Pleb so I’ll take extra friction any day hehe

P.s. dont forget to cover the pinion booth ;p

 So in the same week, Sram release this hanger which allow it to move back in a crash and TRP release a mech with a lock to stop it rotating backwards. Makes sense.

 Nice idea. Syntace do a universal type thing that a few manufacturers use, I’m happy with it on my propain. Easy to get spares

 I would take a hanger made of hardened molten lava at this point. So when it hits something, it does not break...just cause me to crash. Better than having to try and find a new hanger from "yeah, we can order that" bike shops.

 Yea sweet idea dude, why didnt sram think of that one

 How can it be universal if it's only thru-axle compatible? There are bikes out there still using quick release.
