The Crossmarks are the fastest tyres I’ve ever ridden. They really don’t work in even light loam and forget them in the wet but on dry trails they fly.
I’ve currently running tubeless Ignitor 2.1s and they roll well and corner nicely and find grip in most mid to dry conditions.
If you want something fast, light but which also works in a mixture of conditions then you could consider 2.1 High Rollers. They’re small for their size and roll really well and find grip in most situations.
Non-Maxxis wise, Hutchinson Python 2.0s are fantastic tyres. Nearly as fast as the Crossmark and work really well in a range of conditions other than when it’s really muddy and then you need Maxxis Medusa 2.1s which give amazing confidence in the mud and actually work well in middling conditions too.
