Oct 01, 2008· 60 vs 120 TPI pros cons? I'm specifically looking at the Maxxis crosmark 26x2.1 for michigan hardpack. Running as front for me paired to a JBontrager Jones Dry X as a rear, I'm am best catagorized as a begineer racer, The Crossmark will also be rear rubber for the wife who is a novice rider, paired with a Maxxis ignitor on the front.
