I think it's just these particular 'Bora One 50' wheels - Rim brake - I've seen 2 sets on ebay now where the front has delaminated from a decent/heat and a few rear-only sales. But who knows.
The owner of this rear one had that happen to his front too - using correct pads, not a particularly challenging mountain, apparently anyway.Edit: Seems the brake surface was changed in 2017/18 - with new resin and texture.

@Fishfabs do Boras really have a rep for delaminating? They’re widely accepted as the best money can buy, aren’t they?
