The only issue I’ve read about is the rear axle is still QR, so disc positioning is not exactly the same each time you put the wheel in, which leads to more caliper adjustments or rubbing. Sounds small but could be a pretty annoying thing to live with.
Also, I’ve heard the disc frame feels less comfortable, with stiffer forks and chainstays.
I’m using a roval QR and it tightens up a lot more then a thru axle. no problem lining up the disc at all. Don’t really understand why it’s QR rear and thru axle front but don’t be put off.
