Today I tried...

...Maxxis CrossMark 2.1". It's a excellent directional tyre for XC. Grips like glue, unlike Ritchey Z-Max Premonition 2.1" that grips a lot less.

Maxxis CrossMark 2.1" [52-559], kevlar, 29.90€

Ritchey Z-Max Premonition 2.1" Comp [50-559], steel bead, 9.90€

CrossMark excells Premonition in everything except durability/reliability.
