MAXXIS Aspen ST 29 X 2.40 (new 2025)

The Maxxis Aspen ST is a super-fast, short-track (ST) and cross-country race tire, optimized for dry, hardpack, and grassy terrain. It's a sleeker, lower-profile version of the classic Aspen, built for maximum speed in short-distance, high-intensity XC formats like short track and criterium-style MTB races.
