They said it couldn't be done…
The Double Mullet Setup combines the low gear of a typical 1x MTB setup with the high gear of a Road double setup.
To make the road shifters work with the MTB derailleur, a 3D printed pulley is used to convert and change the pull rate. The road shifter is basically emulating the Deore MTB shifter.
With some tinkering and out of the box thinking, there is no such thing as derailleur limit.
Overview of used parts:
Crank: Shimano R7100 50/34
Cassette: Shimano Deore 11-51 (11s)
Gear range: 682%
Shifters: Shimano R7000 (11s)
Rear Derailleur: Shimano Deore M5100
Front Derailleur: Shimano R7000
3D printing material: PETG

Yeah, yeah, nevermind the drivetrain: what’s that gorgeous frame?!
What’s the friction shifter doing in the top tube? Looks connected to something bolted to the rear derailleur?
Looks like a great setup but that saddle angle 😲
Kinda want a video of how this thing works
Yeah I’m gonna need to see this in operation please
That RD is fighting for its life back there
WAT ? WAAAT ?
It’s the most awesome thing I’ve seen since a while !
I hope you write down / publish some insights or even breakdown of this experiment.
Very nice!
I’ve been running and old 2X9 setup for a decade, 46-34 chainrings with 11-36 cassette on a Deore derailler and inverted B screw
Love it. but I’ll stick with my SS
Do you have details on the RD pulley? Would you share the files?
I’m curious about the poles on your frame bag as well. Are they structural to the bag or part of your tent?
Is this because you hate pinion transmission?
As a singlespeed bikepacker this makes me SICK! Nice work OP!
