3C MAXXTERRA
An intermediate compound configuration used in select mountain tires. 3C MaxxTerra is softer and offers more traction than 3C MaxxSpeed, yet provides better treadwear and less rolling resistance than MaxxGrip.
EXO Protection
EXO is a cut- and abrasion-resistant material added to the sidewalls of many Maxxis mountain bike and gravel tires.
This densely woven fabric is lightweight and highly flexible, ensuring that the performance of the tire remains unaffected. Choose EXO Protection for enhanced durability for gravel, XC, and light-duty trail riding.
