The Maxxis Aspen AT Mountain 29 120 TPI Maxxspeed/Exo/Tr tire featured here at Escapa is an MTB tire designed for riders who want the speed characteristic of the Aspen family but need more grip and confidence on technical, uneven, and varied terrain. Its new tread pattern enhances control without sacrificing the rolling performance typical of a racing tire. As a result, it bridges the gap between pure Racing tires and more aggressive Trail options, offering a versatile solution for modern Cross-country and Downcountry riding.
New Tread Pattern for Modern XC
The tread retains the Aspen’s Rapido DNA but uses an updated design to improve performance on more challenging terrain. The tread pattern is designed to provide greater stability during cornering, braking, and on uneven sections, while maintaining good efficiency during pedaling sections.
This evolution meets the demands of today’s XC courses, where fast sections are combined with technical descents, roots, rock, and varied surfaces.
MaxxSpeed Compound
The MaxxSpeed compound uses a high-silica Formula to reduce rolling resistance while simultaneously improving traction on wet surfaces.
According to laboratory tests published by Maxxis, the MaxxSpeed compound offers approximately 25% less rolling resistance than the previous 3C MaxxSpeed, using the same tread pattern, construction, and pressure. Under real-world conditions, the brand estimates that it can save up to one minute in a 90-minute race.
EXO Protection on the Sidewalls
EXO Protection technology adds a cut- and abrasion-resistant fabric to the sides of the tire. This reinforcement is lightweight and flexible, so it increases protection without significantly compromising the tire’s flex or performance.
EXO Protection is particularly useful on trails with rocks, roots, and uneven terrain, where the sidewalls are exposed to impacts and abrasion.
120 TPI Casing
The single-ply, 120 TPI casing provides a flexible and lightweight construction designed to improve ground compliance and reduce rolling resistance.
This structure delivers sensitivity and grip over small irregularities—qualities that are especially important in XC racing and fast downcountry trails.
Tubeless Ready
The Maxxis Aspen AT is Tubeless Ready, so it can be used tubeless on compatible rims with the appropriate valves and sealant. Tubeless setup allows for lower tire pressure to improve traction and control, while also reducing the risk of pinch flats. The sealant can also automatically seal small punctures while riding.
E50 E-Bike Compatible
The tire is E50-rated, meaning it is approved for high-speed e-bikes up to 50 km/h, provided the bike and its use comply with applicable regulations. This rating expands its compatibility with lightweight e-MTBs and XC e-bikes that require a fast, technically capable tire.
