Maker of a few of the wildest machined mountain bike cranks available on the market, 5Dev turns their consideration to highway & gravel bikes with a game-changing UDH Mullet Mod for non-UDH bikes. What it means is that you may 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 motorbike that does NOT have a UDH.
Sure, for the time-bring it’s Specialised solely. However, we will’t think about that may final without end, as this might actually be a game-changer for updating tons of present bike!
Why not make highway and gravel bikes UDH & T-Sort appropriate?
Micro-refresher right here, first. SRAM spent a couple of years convincing the bike-producing world that the common derailleur hanger – or UDH – was the best way of the long run. Mountain biking makers acquired on board fairly rapidly.
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 might bolt the derailleur on to your body, guaranteeing improved stiffness, excellent 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 highway bikes and gravel bikes have been slower to get on board, as there wasn’t as a lot demand for that broad 520% 1x gearing unfold.
Not less than, there wasn’t earlier than. Now, loads of gravel riders need that 1x simplicity. They need that mega Mullet gearing vary that mixes highway dropbar shifters with huge MTB cassettes. However the overwhelming majority – even with a few of the most creatively revolutionary 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 aspect of your Specialised bike’s carbon dropouts. On the within, it will connect with the identical interface as Specialised’s personal replaceable derailleur hanger. And on the skin it areas every part 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 presumably, it might imply the derailleur can be eliminated whenever you take away the rear wheel/axle. However possible many house owners of present Specialised highway 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 highway 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 verify that it’s going to match present Roubaix and Tarmac highway bikes, as effectively.
Additional dialogue of compatibility says that it “suits most 12x142mm by means of 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 might make choices to suit different bikes/bike manufacturers down the highway.
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 US.
But whereas that appears like an exorbitant value for a derailleur hanger mod, it’s truly a reasonably full improve package deal. For fifteen-hundred bucks 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 elements themselves ($650, $150 & $600, respectively), making the 5Dev addition sound down proper inexpensive!
Oh, and yet another factor…
Prototype 5Dev Aero Titanium Cranks for highway & 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 highway and gravel bikes. 5Dev is tight-lipped on the main points apart 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 easy outer floor and smoother rounded edges for cleaner appears and aerodynamics.
We’ll be protecting ears and eyes open for extra particulars!
