I’ve got about 3 rides on my BC UST rubber queens now (2.4 front, 2.2 back), the 2.4 is really good on the front, plenty of grip, the tyres also roll suprisingly fast, but anything probably would coming from Nevegals.
I’ve been riding somewhere new recently, and the ground is still a little soft (damp) and quite loamy, the rear tyre doesn’t offer as much grip as stuff I have used before; Nevegal, Excavator, Ignitor. But that may have sometihng to do with it being loaded with mud and me not being able to get up enough speed to clear it.
I’d definitely get one for the front again but would want something a bit spikier for the rear, maybe a baron? Also, the 2.4 isn’t that big, isn’t only marginally wider than a 2.35 nevegal, the volume is huge though and with low pressure (I’m 28ish front, 26ish psi rear) the grip on roots and rocks is really good.
