Maxxis Crossmark 120 TPI UST Folding Tire 26x2.10
The CrossMark is the dramatic evolution of the cross country racing tire. The nearly continuous center ridge flies on hardpack, yet has enough spacing to grab wet roots and rocks.
This is an excellent tire for hard pack singletrack! Very fast, bites into cornering. Used this tire in Indiana and loved it. After moving to Colorado, I found some downsides to this tire. Mainly, climbing long distances in loose rock. A lot of slip. Overall, if all you ride is hard pack, it's an excellent tire! If you ride in more loose rock and gravel, I'd look for something with more grip.
