Maker of a number of the wildest machined mountain bike cranks in the marketplace, 5Dev turns their consideration to street & gravel bikes with a game-changing UDH Mullet Mod for non-UDH bikes. What it means is you could run a brand new direct mount SRAM mountain bike Transmission (T-Sort) derailleur on Specialised bikes which have a standard hanger.
That’s proper, T-type derailleurs on a motorcycle that does NOT have a UDH.
Sure, for the time-bring it’s Specialised solely. However, we are able to’t think about that can final eternally, as this might actually be a game-changer for updating tons of present bike!
Why not make street and gravel bikes UDH & T-Sort appropriate?
Micro-refresher right here, first. SRAM spent just a few years convincing the bike-producing world that the common derailleur hanger – or UDH – was the best way of the longer term. Mountain biking makers received on board fairly shortly.
And that later turned out to be as a result of SRAM had an all-new direct-mount model T-Sort MTB rear derailleur & Transmission within the works. With out tons of various hangers, they may bolt the derailleur on to your body, guaranteeing improved stiffness, good alignment, and promising higher shifting. All you wanted was a UDH-equipped body. Tons of mountain bikes have already made the leap, so there’s tons of appropriate choices.
However street bikes and gravel bikes have been slower to get on board, as there wasn’t as a lot demand for that large 520% 1x gearing unfold.
A minimum of, there wasn’t earlier than. Now, loads of gravel riders need that 1x simplicity. They need that mega Mullet gearing vary that mixes street dropbar shifters with huge MTB cassettes. However the overwhelming majority – even with a number of the most creatively progressive new gravel bikes – don’t have UDH-ready bikes.
So, 5Dev needed an answer. What’s their Mullet Mod?
Enter the bolt-on 5Dev Mullet Mod for Specialised bikes!
Put merely, this appears to be only a smartly-designed thru-axle finish nut and set of spacers.
We’ve not seen an exploded diagram of it but. However presumably, it is a mixture of spacers on both facet of your Specialised bike’s carbon dropouts. On the within, it will hook up with the identical interface as Specialised’s personal replaceable derailleur hanger. And on the surface it areas all the pieces out to the proper width for the T-Sort SRAM MTB derailleur. Tying it collectively is probably going a particular thru-axle and a bolt that holds all of it collectively.
5Dev says that there are “no modifications wanted. It’s a bolt on mod.” So probably, it may imply the derailleur could be eliminated while you take away the rear wheel/axle. However probably many homeowners of present Specialised street and gravel bikes would take that compromise to suit the newest mullet drivetrain onto their bikes.
What bikes does it match?
First off, 5Dev says that it’s made for “choose specialised street and gravel frames“. They go on to elucidate that it’s “splendid” for the Diverge and Cruz line-ups, which incorporates the ‘full-suspension’ Diverge STR. Individually additionally they affirm that it’ll match present Roubaix and Tarmac street bikes, as effectively.
Additional dialogue of compatibility says that it “suits most 12x142mm by 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. Presumably, 5Dev may make choices to suit different bikes/bike manufacturers down the street.
And the way a lot does it value?
Right here’s the trick. The 5Dev Mullet Mod for Specialised bikes prices $1500, and is ONLY accessible in the USA.
But whereas that seems like an exorbitant worth for a derailleur hanger mod, it’s truly a reasonably full improve bundle. For fifteen-hundred bucks you get the whole 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 components themselves ($650, $150 & $600, respectively), making the 5Dev addition sound down proper reasonably priced!
Oh, and another factor…
Prototype 5Dev Aero Titanium Cranks for street & gravel
Did you discover these cranks on the Specialised gravel bike there? That’s an as-yet-unreleased set of CNC-machined 5Dev Aero Titanium Cranks for street and gravel bikes. 5Dev is tight-lipped on the small print aside from to say ‘stay-tuned’. They clearly are SRAM direct-mount crankarms that share the exactly machined ends of their signature MTB cranks. However they’ve a clean outer floor and smoother rounded edges for cleaner seems to be and aerodynamics.
We’ll be maintaining ears and eyes open for extra particulars!
