ASPEN STThe 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.Key Features Ultra Low-Profile Tread:Minimizes rolling resistance for maximum acceleration and speed on smooth terrain. File Tread Center with Minimal Knobs:Provides just enough grip while maintaining a slick-like feel for fast rolling. Lightweight Race Casing:Prioritizes speed and responsiveness over durability—ideal for race day, not rough trail use. 3C MaxxSpeed Compound (select models):Enhances speed while still giving predictable handling in corners. Tubeless Ready (TR):Supports low pressures for better traction and control without flats. Available Sizes:Mostly in 29x2.4 WT format, optimized for modern wide XC rims. Ideal For Short Track XC Racers who need a super-fast tire with minimal rolling resistance. UCI XC racers or elite riders targeting smooth, dry courses with few technical features. Riders looking for a rear tire to pair with a slightly more aggressive front (like a Maxxis Rekon Race or Aspen). Not ideal for wet, loose, or rocky terrain—best reserved for race day on groomed tracks.
