Shimano has filed a patent for a new derailleur hanger design that, quite frankly, has us scratching our heads. Along with a UDH-style solution for mounting a hanger to the dropout, this so-called “bracket apparatus” has a second forward mounting point that looks to mount a battery, or some other electronic device, from the inboard face of the chainstay.
Our first thoughts? Oh, Shimano is bringing the derailleur’s battery outside, but then housing it on the frame instead. Fair enough, right? It seems reasonable to bring it out for more accessibility and less hassle with internal cable routing, but relatively speaking, having it out of harm’s way would be good too. Looking more closely at the fresh patent (US 20230166813 A1), we believe this new arrangement could form the basis for execution of more exciting technology; a self-charging solution, or, if we really think outside the box, it could even be the infrastructure necessary for the execution of Fox’s Suspension Enhancing Hub and Derailleur Assembly .
With potential involvement of a proposed hub dynamo, an integrated cassette cleaner and chain stabilizer, this bracket device, thanks to its secondary mounting device, brings with it some interesting uses beyond the simple mounting of a rear derailleur.

Before we allow our minds to run wild, let’s focus on the structure of the proposed derailleur hanger from Shimano. Much like the SRAM UDH design, the Shimano “Bracket Apparatus” ties in the thru-axle mounting of the rear wheel with the […]
