The Maxxis Aspen pushes the limits of a lightweight XC designed to have a minimal rolling resistance. The Aspen is designed with a high-volume casing to smooth out the roughest roots and rocks while the dual compounds give optimal traction in the corners. If crossing the finish line first is your top priority then the Aspen was designed for you.

This densely woven fabric is also lightweight and highly flexible ensuring that the performance of the tyre remains unaffected. Choose EXO Protection for exceptionally rocky treacherous trails where the chance of sidewall cuts and abrasions is high Tubeless Ready Tubeless 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 since there is no tube. 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
