Wheels Manufacturing adds Dropout-E to extend any hanger to fit bigger gears

While this isn’t a new concept, it is a new product for Wheels Manufacturing. Much like the Wolf Tooth Components RoadLink, the Wheels Manufacturing Dropout-E is here to make your pedaling a bit easier – or at least allow you to run a larger cassette.

Wheels Manufacturing adds Dropout-E to extend any hanger to fit bigger gears

The idea is pretty simple. The Dropout-E extends the derailleur position by 21mm to allow for more clearance to run a larger rear cog. Designed to work with every standard derailleur hanger and rear derailleur, the adapter bolts to the derailleur hanger, and then the derailleur bolts to the adapter.

When used in a 1x set up, Dropout-E will allow for up to a 42t max rear cog. For double or triple cranksets, the adapter will allow for up to a 40t max cog. And if you’re the Campagnolo type, the adapter will allow for a 36t max cog with any Campagnolo crankset.

Machined from 6061 aluminum, the adapter includes a steel fixing bolt and comes in an anodized black finish for $18.

Wonder if they licensed it from Wolf Tooth? I think that the Roadlink has had a patent on it.

If not licensed that’s a pretty blatant knockoff- I’d have expected better from Wheels.

Sorry to say but I couldn’t expect anything better from Wheels. Haha.

I wonder about the patent-pending status for the Wolf Tooth Components RoadLink?

Is this sidestepping a possible infraction, legitimately licensed from WTC, or destined for a legal issue?

LOL, well done D-con. Great minds…

For reference, here is the WTC patent:

You’d have think they would have skipped the bolt on and just offered commonly “wide ranged” bikes to have a longer hanger option!

Does patent-pending mean that approval is imminent? Either way, That may be a pretty thin patent and Wolf Tooth may not be able to spend the necessary $$ to attempt to protect it in court.

Better do your math carefully. It’ll be really easy to get too far outside of Shimano/SRAM/Campy’s tooth capacities and ruin your frame with chain-suck..

It is no guarantee that they will receive a patent. It is fair warning to any and all competitors that they have filed for protection. It’s a “copy at your own risk” sort of affair, AFAIK.

At the point a patent is officially issued, WTC would be within their rights to pursue legal action against any who may have infringed on their design and/or continue to do so.

If no patent is issued, anyone can make it with no consequences or considerations for WTC.

Looks like it’s been granted: https://patents.google.com/patent/USD798197S1/

IANAL, but that Wolf Tooth “patent” is actually an ornamental design patent. It’s a claim on how it looks, not how it works.

Well funded companies used to use these patents to scare away competition from small startups, back before the internet made information easier to find. (Now get off my lawn!)

More interesting is that Wolf Tooth went to the trouble of filing for an ornamental design patent in the first place.

Why not file for a proper patent on the design itself? Unless they couldn’t because of what the lawyers call “prior art”?

After all, derailleurs shifted by a cable have been around for 80 years, and bicyclists are notorious tinkerers. It’s entirely possible that someone could have created and documented a similiar design in that time.

John,
An ornamental patent keeps companies from knocking off the appearance of an object. It’s sometimes done for the reason you cite- but also to reduce the potential for confusion in the marketplace (ie: Wheels’ dangler looks just like the RoadLink so must work/be the same). It also prevents someone from simply taking an existing product and copying it without putting in any product development work (something we see out of China pretty regularly).

Why would anybody dish out 18 bucks when you can get the exact item for 4$ online?…with shipping 😀

Because if you only buy knockoffs we’ll all find other work and there won’t be any new product development going forward.

Wheels should have flexed their machining muscle and come out with direct fit hangers that were a bit longer. 21mm is too much, and it moves the upper pulley too far from the smaller cogs.
In the end, though, it’s a very poor band aid anyway. People would be better off with a mountain bike derailleur and TanPan. Works so much better.

The TanPan is a bit of a bandaid, too. It can make shifting sluggish.

My 2x road bike fit an 11-36 cassette with an Ultegra GS derailleur using the existing b-screw and shifts as crisply as an 11-32, and my 1x gravel bike runs a 10-42 cassette with an XT/MTB Di2 derailleur and road shifters (and could easily fit a 10-46).

Been down this road. It’s really just better spending the ~40-50 bucks extra and buy a long cage derailleur that can handle a 40 (at least for Shimano) considering you’re going to need to change chain length anyways this isn’t something you’re going to want to pop on and off every two weeks for trips to the mountains and the R8000 long cage shifts beautifully the only downside is an almost non existent aero loss and a few grams of weight.

What 11 speed road or man derailleur that can run a 40 costs only $40-50?

The R8000 you cite is rated for 34t max (though it reportedly can handle more) costs $75+
