Running regular 29x2.4” tires in the 120mm Mattoc the AC is 1cm taller than the setup on the B17 (which runs a 130mm Boost RS on the same chassis). That’s not even 1/2 a degree change to HTA and STA at sag - especially since I run the rear fairly firm.
With the 29+ SE4 I’m running everything is awesome with the handling except the seat angle which starts to get a bit slack. I compensate by running the saddle forward on a zero-offset post and it suits my needs well.
If I was custom building a Rift Zone I’d crank the STA a couple degrees steeper for my specific setup but the rest of the geo is great with 120mm/29+
