    HG to Microspline... help?!

    So I have a new SLX 1x12 coming my way and just realized I made a huge mistake... I have an HG freehub and these all require the new Microspline.

    Current hub is Formula DHL1971 on my Cannondale Fat CAAD.

    I can't figure out - will this part allow me to convert my freehub? Or is it DT Swiss specific?

    https://www.amazon.com/gp/product/B0...F3KCF7YAD3R431

    Am I screwed?

    freehub bodies are ALL hub specific.

    You can run the drivetrain, but you'll have to use a 12spd cassette with an HG interface, like a Sunrace or something.

    Well - you just saved my day. I can drop $70 into the Sunrace and I'll be in for the total cost of SRAM NX, which I should've just gotten

    I could also spring for the SRAM NX.
    Any other suggestions for a 12-speed on HG hub?

    I am running the Sunrace 12 speed cassette with a Shimano shifter and derailleur, and it has been fine for a few hundred miles of hard riding on my mountain bike. Cassettes are consumable parts, they all break eventually.

    They're fine. I've got sunrace 11spd cassettes on 2 different bikes and there's absolutely nothing wrong with them aside from the fact that they're a little heavy. But that's a sub-$100 HG cassette for you.

    Yes, NX Eagle is an option. Visit the drivetrain forum. There's a bunch of discussion about a Chinese ZTTO cassette, too.

    There aren't a ton of options for 12spd on an HG hub. They're mostly going to be from companies that sorta operate on the fringes, aside from NX Eagle. It's probably going to be awhile before Deore makes it to 12spd, but I could see that being on an HG hub. That is, unless Shimano decides that MicroSpline will completely replace HG beginning at 12spd. That's a possibility, too.

    The other option you have is what NYrr496 said...put a better hub in your wheel. DT Swiss would be a solid upgrade option that's not too expensive. More expensive than buying a 12spd HG cassette, but it would make it easier for you going forward to just buy Shimano cassettes.

    sunrace is a bad design. I had two cassettes fail the exact same way, the aluminum carrier separated from the gear. I am in no way a powerhouse, yet both failed literally the same way.

    It was enough for me to swap everything i own to XD driver and switch over to the GX cassette.

    *at work, can't post pics. I will when i get home*

    ooh, i have two vids on youtube from when it happened... first vid-

    I did the exact same thing to a Shimano XT 10spd while on a ride with my then 8yo daughter. And still riding a CS-M771 today.
    After 2 of them to myself I may shy away, but translating your experience to my potential I wouldn't worry too much about.

    I soft pedaled in the lower 3 an additional 3 miles to the car.
