The Udden features tightly-spaced, low-profile center knobs with aggressive cornering tread for an efficient tire that works well across hardpack, dirt and gravel. The Udden is suited for long days of exploration and lining up on race days where anything could be around the next corner. As the results of years of R&D we have created the specially-tuned Rubberforce G tread compound and Stage 5S Armor construction giving the Udden impressive grip in the dirt and improved ride quality and abrasion resistance.
