Rollin, Rollin, Rollin....
...get those wheels a rollin! I ride on dry hardpack to loose dirt conditions, and that's what these tires are made for! The grip is great on the switchbacks and I am able to keep my speed effortlessly on the XC sections thanks to the low rolling resistance(I got the 70a). The sidewalls feel a little thin, but haven't had any issues. Not made for mud, but kick a$$ in dry conditions!
