Got my XMCs from gambacicli, but looking on their website seems to just have the old ones.
Two further comments, neither of which you asked for, but never mind:
I don’t particularly like riding the DTSwiss carbon, they’re too stiff and just rebound all over the place. Sounds like you want them for racing rather than all mountain so may be ok.
More relevantly, this:
Pretty sure roval now have a better warranty policy for the first two years.
I had a long correspondence with UK warranty about a crack on my XMCs. Their position was that a rock had clearly bounced up and hit the rim top and cracked it. My view was no shit, that’s what happend when you go mountain biking ( especially all mountain). My aluminium rims are absolutely covered in dings from multiple rock hits, but still work fine
They refused to sort it and wanted £260 for a new rim. I didn’t see the point in spending that just to get back to ” don’t use these wheels anywhere there may be loose rocks” so declined.
I’ve bought 4 aluminium DTSwiss wheels since then, but wouldn’t go near them for carbon again.
