Oh no, that sounds rubbish. most of the last few years it's been on Red Bull TV, and here in the UK On the BBC website/Red button, with two different commentary options.
One hopes something is sorted; MTB on anything other than RBTV is just wrong; the Olympics showed that.
Just saw that UK will have a separate link (with only english commentary) to watch on RedBull TV
Albania, Slovakia, Sweden and UK will have this link, and Italy and France will have a dedicated one too with only their main language available.
From the usual one, the only european countries with permission to watch are Czech Republic, Germany and Norway. Switzerland will be able to watch but with a delay of 1 hour.
