Maker of one of the wildest machined mountain motorbike cranks available on the market, 5Dev turns their consideration to street & gravel motorcycles with a game-changing UDH Mullet Mod for non-UDH motorcycles. What it manner is that you’ll be able to run a brand new direct mount SRAM mountain motorbike Transmission (T-Sort) derailleur on Specialised motorcycles that experience a standard hanger.

That’s proper, T-type derailleurs on a motorbike that does NOT have a UDH.

Sure, for the time-bring it’s Specialised handiest. However, we will’t consider that may closing without end, as this may in reality be a game-changer for updating lots of present motorbike!

Micro-refresher right here, first. SRAM spent a couple of years convincing the bike-producing international that the common derailleur hangeror UDH – was once the way in which of the long run. Mountain cycling makers were given on board lovely temporarily.

And that later became out to be as a result of SRAM had an all-new direct-mount taste T-Sort MTB rear derailleur & Transmission within the works. With out lots of various hangers, they may bolt the derailleur immediately on your body, making sure advanced stiffness, best possible alignment, and promising higher moving. All you wanted was once a UDH-equipped body. Heaps of mountain motorcycles have already made the jump, so there’s lots of appropriate choices.

However street motorcycles and gravel motorcycles had been slower to get on board, as there wasn’t as a lot call for for that large 520% 1x gearing unfold.

No less than, there wasn’t prior to. Now, various gravel riders need that 1x simplicity. They would like that mega Mullet gearing vary that mixes street dropbar shifters with large MTB cassettes. However the overwhelming majority – even with one of the maximum creatively leading edge new gravel motorcycles – don’t have UDH-ready motorcycles.

So, 5Dev sought after an answer. What’s their Mullet Mod?

Put merely, this appears to be only a smartly-designed thru-axle finish nut and set of spacers.

We’ve now not observed an exploded diagram of it but. However probably, this can be a aggregate of spacers on all sides of your Specialised motorbike’s carbon dropouts. At the inside of, it could hook up with the similar interface as Specialised’s personal replaceable derailleur hanger. And at the outdoor it areas the whole thing out to the right kind width for the T-Sort SRAM MTB derailleur. Tying it in combination is most likely a distinct thru-axle and a bolt that holds all of it in combination.

5Dev says that there are “no adjustments wanted. It’s a bolt on mod.” So most likely, it will imply the derailleur could be got rid of whilst you take away the rear wheel/axle. However most likely many homeowners of present Specialised street and gravel motorcycles would take that compromise to suit the newest mullet drivetrain onto their motorcycles.

What motorcycles does it are compatible?

Specialized Diverge STR gravel bike dropout

First off, 5Dev says that it’s made for “make a choice specialised street and gravel frames“. They cross on to provide an explanation for that it’s “excellent” for the Diverge and Cruz line-ups, which incorporates the ‘full-suspension’ Diverge STR. One after the other in addition they ascertain that it’ll are compatible present Roubaix and Tarmac street motorcycles, as neatly.

Additional dialogue of compatibility says that it “suits maximum 12x142mm via axle frames” with 5Dev’s patent pending design. The figuring out issue goes to be the width of the body on the dropout AND the constant interface for a replaceable derailleur hanger. Possibly, 5Dev may just make choices to suit different motorcycles/motorbike manufacturers down the street.

And what sort of does it price?

Right here’s the trick. The 5Dev Mullet Mod for Specialised motorcycles prices $1500, and is ONLY to be had in the US.

But whilst that feels like an exorbitant value for a derailleur hanger mod, it’s in truth a beautiful entire improve bundle. For fifteen-hundred greenbacks you get your entire bolt-on 5DEV UDH Mullet Mod, plus a brand new SRAM XX SL AXS rear derailleur, an XX SL flattop chain, and an XX SL 10-52T cassette. That’s already $1400 for the SRAM portions themselves ($650, $150 & $600, respectively), making the 5Dev addition sound down proper reasonably priced!

Oh, and yet another factor…

Did you understand the ones cranks at the Specialised gravel motorbike there? That’s an as-yet-unreleased set of CNC-machined 5Dev Aero Titanium Cranks for street and gravel motorcycles. 5Dev is tight-lipped on the main points as opposed to to mention ‘stay-tuned’. They obviously are SRAM direct-mount crankarms that proportion the exactly machined ends in their signature MTB cranks. However they have got a clean outer floor and smoother rounded edges for cleaner appears to be like and aerodynamics.

We’ll be maintaining ears and eyes open for extra main points!
