Maxxis Aspen ST Tire

The Maxxis Aspen ST Tire is a purpose-built cross-country race tire engineered for maximum speed in dry, fast-moving conditions. Developed with modern short track XC racing in mind, the Aspen ST features an ultra-low-profile tread design that prioritizes rolling efficiency, acceleration, and race-day responsiveness for riders chasing podium-level performance.

Often referred to by racers as the “Fastpen,” the Aspen ST takes the proven speed-focused character of the standard Aspen platform and pushes it even further toward pure race efficiency. The tightly packed, minimal tread pattern reduces rolling resistance dramatically, helping riders carry speed effortlessly across hardpack terrain, dry race courses, and smooth singletrack. Whether sprinting out of corners, attacking climbs, or maintaining momentum through flowing sections, the Aspen ST is designed to feel exceptionally quick under power.

To complement its race-focused tread design, Maxxis pairs the Aspen ST with its high-performance MaxxSpeed rubber compound. Optimized specifically for XC competition, this compound enhances rolling speed while maintaining predictable traction and responsive handling in dry conditions.

Available in lightweight 120 TPI + EXO and ultra-light 170 TPI + EXO Team Spec casings, the Aspen ST balances race-ready weight savings with trail durability and sidewall protection. The EXO sidewall reinforcement helps guard against abrasions and cuts without significantly increasing weight, making the tire suitable for aggressive XC racing and high-speed technical sections alike.

The 2.40-inch versions are optimized around modern 30mm internal-width rims, creating a stable tire profile that improves cornering confidence and ride feel at lower pressures. Tubeless Ready construction further enhances performance by allowing riders to run lower tire pressures for increased traction, reduced rolling resistance, and improved flat protection.

For riders seeking every possible advantage in dry cross-country racing conditions, the Maxxis Aspen ST Tire delivers exceptional speed, lightweight efficiency, and race-proven performance.
