I think there’s maybe room in the tall person market. Lennard is stuck in the 90s geometry wise and obsessed with 220mm cranks and such so imo those bikes are pretty bad. Dirty6er is it’s own super weird thing.
That said, there’s not that much money in mountain bikes, especially hard tails. And there aren’t that many super tall people either.
So the answer is I have no idea.
