Maxxis Aspen ST MaxxSpeed EXO MTB Tire

The Aspen ST is an ultra-low-profile race tire designed primarily for short track XC use. Sometimes referred to as the "Fastpen," this tire is sure to give any racer an edge in dry conditions.

MaxxSpeed

The new MaxxSpeed (2023) is Maxxis' top-shelf rubber compound for XC racing. It's a high-silica content compound which reduces rolling resistance while also enhancing wet traction. Compared to the previous 3C MaxxSpeed, the new compound has approximately 25% less rolling resistance in a lab setting (using the same tread pattern, construction, and tire pressure). In a real world setting, testing shows the new compound can save up to a minute over the course of a 90-minute race.

EXO

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.
