Wheels Mfg. gives UDH bikes a direct-mount hanger for Shimano derailleurs

Got a bike that’s compatible with SRAM’s UDH (Universal Derailleur Hanger) but prefer Shimano? Until Shimano launches their own solution, Wheels Manufacturing has one for you with their new direct-mount derailleur hangers for Shimano’s road/gravel and mountain bike groups.

Wheels Mfg. is offering two models to fit any type of bike, both of which replace the B-link on Shimano’s derailleurs. This eliminates one extra point of movement and eliminates just a bit of wiggle room, which they say provides a stiffer mounting point and crisper, more precise shifts.

The Dropout 562 for gravel fits Shimano-Dura-Ace (R9100 and R9150), Ultegra-(R8000, R8050, RX800, and RX805), 105 (R7000), and GRX-(RX810, RX812, RX815, RX817, and RX400) groups.

The Dropout 652 for mountain bikes fits Shimano Saint (RD-M820), Deore (RD-M610, RD-M5120, RD-M4120), Deore XT (RD-M8000, RD-M8050), SLX (RD-M7000-10, RD-M670), and Altus (RD-M2000) groups. Both have the same ability as UDH hangers to rotate backward in an impact, helping save your derailleur during a crash.

Production versions will be black anodized 6061 aluminum and retail for $60. They mount through the dropout, just like a UDH hanger, using the same M12x1.0 thread pitch as UDH-compatible thru axles…so, if your bike came with a UDH hanger, the stock thru axle will work with this hanger.

While SRAM’s T-Type transmission groups are amazing, perhaps the biggest benefit to all riders is the standardization of the derailleur’s position in space, which allows products like this to exist and improve shifting for older and other brand derailleurs, too.

Not sure what you mean. UDH was introduced 4 years ago. I reached out to Wheels Mfg about this a while ago and didn’t get a response, glad to see it come to market though.

With UDH how will you align the hanger? With a Park DAG 2.2 tool? Will it work? 12 speed is super finicky… Has anyone thought this through? I love this Wheels mfg adapter, they make some clever parts like my Wheels threaded BB installed in a press fit Giant Revolt frame.

Why wouldn’t it work? UDH is still just a derailleur hanger, even if the frame interface is different.

UDH big claim to fame is you can stand on the derailleur and it does not bend or break. With this in mind it would seem to be much more difficult to bend the hanger back into alignment with a Park DAG tool.

No, that’s the advantage of the SRAM T-Type derailleur, which uses the UDH frame fitment. There is no alignment for T-Type derailleurs, you just bolt it on. For UDH hangers like this, you align it the same way you would any other hanger.

It’s aluminum, nothing is being bent back into shape. It’s being replaced if damaged.

Tell me you have never worked in a bike shop without telling me you have never worked in a bike shop.

Plenty of bikes come with replaceable der hangers out of whack that are brand new and no shop replaces them. They get out the Park Tool derailleur alignment tool and align it.

If it’s fubar, that’s a different story.

What a condescending prick you are. He’s right. Aluminum hanger is a sacrificial part. It is meant to be replaced. Unwillingness of bike mfgs to stick to one hanger standard is whole another story…

Uhm, aluminum RD hangers are routinely aligned. If you’re working on bikes and you don’t make sure that aluminum RD hanger is aligned before putting that new bike on the floor or sending it home with the new owner, you shouldn’t be allowed to work on other people’s bikes.

I think you’re confusing the UDH, which is a derailleur hanger for direct-mount frames, with the new SRAM direct mount derailleurs. The UDH can be aligned like any other derailleur hanger.

This UDH thing is crazy, and it is going to start a war. I cannot wait to see Shimano’s response to all this.
