( / )

The Maxxis Aspen is one of our premier XC race tires. A low center tread height allows the Aspen to roll quickly but substantial - for XC - side knobs provide cornering traction.

MaxxSpeed

The new MaxxSpeed (2023) is our 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, our 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.

Tubeless Ready

Tubeless ready tires provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tire; and less chance of flatting because there is no tube. Tubeless ready tires are denoted by the letters “TR” on the sidewall.
Tubeless ready tires must be mounted to tubeless compatible rims and require the use of a liquid sealant to maintain pressure. Liquid sealants have the added benefit of sealing small punctures. Be sure to check your sealant regularly and refresh as needed as it will dry out over time.
Liquid sealants should only be used in the following types of tires: tubeless road, tubular, and tubeless ready. The use of liquid sealants in any other Maxxis tire will void the warranty.

Wide Trail XC (WT XC)

Maxxis recommends using 2.40″ Wide Trail XC tires on 30mm internal rims. The tires are compatible with rims as narrow as 25mm, but we do not recommend exceeding 30mm wide.
