Maker of one of the wildest machined mountain motorcycle 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 approach is that you’ll be able to run a brand new direct mount SRAM mountain motorcycle Transmission (T-Sort) derailleur on Specialised motorcycles that experience a traditional 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 believe that can closing ceaselessly, as this may truly be a game-changer for updating lots of current motorcycle!

Why now not make street and gravel motorcycles UDH & T-Sort appropriate?

Micro-refresher right here, first. SRAM spent a couple of years convincing the bike-producing global that the common derailleur hangeror UDH – used to be the best way 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 might bolt the derailleur without delay in your body, making sure stepped forward stiffness, best alignment, and promising higher transferring. All you wanted used to be 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 were slower to get on board, as there wasn’t as a lot call for for that broad 520% 1x gearing unfold.

No less than, there wasn’t prior to. Now, quite a few 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 cutting edge new gravel motorcycles – don’t have UDH-ready motorcycles.

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

Input the bolt-on 5Dev Mullet Mod for Specialised motorcycles!

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

We’ve now not noticed an exploded diagram of it but. However probably, it is a mixture of spacers on all sides of your Specialised motorcycle’s carbon dropouts. At the inside of, it will connect with the similar interface as Specialised’s personal replaceable derailleur hanger. And at the out of doors 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 changes wanted. It’s a bolt on mod.” So perhaps, it would imply the derailleur could be got rid of while you take away the rear wheel/axle. However most likely many house owners of current Specialised street and gravel motorcycles would take that compromise to suit the newest mullet drivetrain onto their motorcycles.

What motorcycles does it have compatibility?

Specialized Diverge STR gravel bike dropout

First off, 5Dev says that it’s made for “make a choice specialised street and gravel frames“. They pass on to give an explanation for that it’s “preferrred” for the Diverge and Cruz line-ups, which incorporates the ‘full-suspension’ Diverge STR. One at a time in addition they verify that it is going to have compatibility present Roubaix and Tarmac street motorcycles, as neatly.

Additional dialogue of compatibility says that it “suits maximum 12x142mm thru 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. Probably, 5Dev may just make choices to suit different motorcycles/motorcycle manufacturers down the street.

And what kind of does it value?

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

But whilst that feels like an exorbitant value for a derailleur hanger mod, it’s in fact a beautiful whole improve bundle. For fifteen-hundred greenbacks you get the 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 inexpensive!

Oh, and another factor…

Did you realize the ones cranks at the Specialised gravel motorcycle 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 rather than to mention ‘stay-tuned’. They obviously are SRAM direct-mount crankarms that percentage the exactly machined ends in their signature MTB cranks. However they’ve a easy outer floor and smoother rounded edges for cleaner seems to be and aerodynamics.

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