The Good: Rolls fast Good grip Drifts predictably Pretty light
The Bad: Short knobs get overwhelmed in deep mud Can get flats in extremely rocky terrain (especially at lower pressures)
I've been running the 2.25 crossmark as the rear tire on my trail bike for years. I pair it with a minion DHF and have really come to love this combination. The crossmark has surprisingly good grip--much better than you would think just looking at it. It rolls very well, and I can notice a big difference compared to say a high roller or other knobbier tires. In corners it holds quite well and drifts super predictably. Paired with a larger/knobbier tire like the DHF I can corner really aggressively because I know the rear will let go before the front and that it will do so in a predictable manner. If I lived in the mountains, I'd likely run something a little burlier, but for the piedmont area round me which has lots of roots and rocks but not as much high speed chunder it's a great choice.
