Deity dirty thirty, Azonic makes multiple 30+" bars, Funn makes some wide ones, Syncros makes one, Spank makes one. There are a lot of companies that have wide bars this year.
These are 800mm. They come with cutting markers so you can choose to reduce them down to anything below 800mm and above 680mm. If flat bars aren't your thing, they also offer the bars with a lot of different rises up to 50mm.
