Exactly - XC geo is being pushed by race environment and development and has already pushed the offerings in the trail bike realm. A trail bike is theoretically basically just a burlier, more reliable XC bike with a bit more travel and more "fun" geometry and feel. When race XC bikes are coming out with head angles in the 68º range, then it makes sense that trail bikes should be getting 66º if they're running 140mm forks.Current XC geometry is about as close to road geometry as DH bike geometry is to 120mm trail bike geometry.
Thing is... under a decent XC rider XC geometry makes perfect sense.
Just look at XC riders like Nino or Grant Ferguson ride.
Saddle up they're both more stylish and faster descending than a lot of "DH" riders here.
My roadbike (TCR) has a 73deg HA, a WC XC bike will be between 68-70
My 4X bike's HA is in that range and it's not exactly designed for roads or climbing.
I'm glad bikes are getting rowdier. Just because I want a short travel bike for trail riding doesn't mean I want it to steer like a reversing forklift.
