The spirit of Grav-lo-cross. No but seriously, cyclocross and gravel go here!

Shimano silently introduced a new freehub. Microspline Road. It is a 'normal' Microspline freehub that is 1,85mm longer.
It is not the DA 12s freehub.
My best guess it that they will use that on the new 12s GRX group to make it run 10-44 cassettes.

I have some of those freehub at my place already.
Except they already have a perfectly good MTB 10-45 that works on the MTB Microspline - an extra SKU for 10-44 doesn't make any sense there. Given they exist though, there's clearly some new product in the pipeline.

What a mess ... now 4 different FHs for Shimano 12s. HG, weird DA-HG, MS, MSR ...

They've lost the plot.

Also amazed they let the cat out of the bag like that given how secretive Shimano tend to be and how restrictive they are with partners. Guessing another farce may ensue where it's only 3 or 4 brands that have access to the new design patent initially - per MS.

This is also likely a tacit admission that the HG 12s spacing is too cramped (maybe part of the reason why their 12s road cassettes suck), and MS spacing is still too cramped.

I’m sorry, but that is a DT Swiss freehub body for Microspline. No mention of a new version on DT’s site. What’s the part number?

I dunno man, I reckon Shimano's 12s road cassettes (incluing the 105 level 11-36) are much better than Campy's. And I'm a Campy tragic.

But in reality it’s only 2. HG & MS. HG12 cassettes fit on any 11 speed era cassette body and the likelihood of a road version of MS is slim.

Does it come with a spacer so you could use an MTB cassette on it?

I hope they do a version for old road 240S hubs (non EXP).

I imagine they created this for all the road EXP hubs out there that you couldn't fit the MTB microspline hub on to.

New GRX and a new XTR based Mullet is definitely needed. I think Shimano is missing out on a lot of the market.
It must be the forecast of new cassettes. You can easily fit MTB freehubs on any EXP hubs. Road or Mtb the hubs have exactly the same interface. But, Microspline drivers are allowing for cassettes with 10T sprockets.

The longer MS freehub brings the possibility of a 1x13 drivetrain. Imagine a 12-speed HG+ MTB cassette with one added cog. Perhaps this is Shimano's response to Campy's Ekar? I wouldn't mind a 2x13 drivetrain as well for gravel. A 13-speed 2x cassette with the following ratios would be sweet for gravel: 10-11-12-14-16-18-20-22-24-26-29-32-36

A 2x13 with such a ratio would be great! I’d only start with 11 and add the 15

Why on earth would DT release an as yet unreleased by Shimano freehub pattern? Have you compared it to previous DT MS freehubs or are you assuming it’s new?

There is no reference to a different part number on DT’s site and bearing in mind Shimano’s reluctance to allow anyone to produce AM freehubs when MS came out, I doubt you are talking about a real change.

Shimano have been very quiet about introducing (or making) anything for a few years now, so I'd be reluctant to assume much from an as yet undocumented DT Swiss freehub body.

As for 13 speeds, given these are all likely to have at least 36T (like Ekar, Rotor, etc), then there's no need for extra freehub body width; the larger cogs can just overhang the spokes a bit more. Where the extra width is needed is for small road cassettes, to ensure derailleur to spoke clearance.

I don't think Shimano give a shit what Campag do, and they won't, unless they begin mass producing more stuff in Taiwan or China.

LOL! My first thought as well, when I read that.

Shimano are a very conservative company when it comes to change. They aren’t given to knee jerk reactions. Also, given their attitude to 1X off road, I’d be surprised if they jump to 13 speed any time soon, if at all.

Shimano produces a lot of mid level stuff in Malaysian and all the cheap stuff in China.

Well, I do think they give a shit. Remember Sram coming up with narrow wide chainrings, clutched derailleurs, 12-speed, 1 by drivetrains,vgravel specific groupsets, wide range cassettes...
Guess who adopted all of it a few years later.

Clutched derailleurs - Sram followed Shimano
12 Speed - Campag lead on that
1x - Sram forced that prematurely due to their awful attempts at front mechs
Gravel specific group sets? These all came after GRX was introduced.
