Tire Maxxis Aspen ST 29x2,25 MaxxSpeed, EXO, TR 170TPI

Riders have asked, begged, and maybe even demanded, and Maxxis has finally answered. ASPEN NEW MODEL! Maxxis Aspen ST special edition model, which Nino has been riding and winning with for several years.

Maxxis is offering a limited production run of the Aspen ST model with a 170 TPI casing version. Until now, these tires were reserved only for the best race teams - now finally available for purchase.

Lighter than the regular Aspen and with a lower and faster tread pattern. Particularly suitable for fast gravel riding. 

Weight: approx. 610g 

170 TPI 

29x2.25 (57-622)

Tubeless Ready

Tubeless ready 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 because there is no tube. Tubeless ready tires are denoted by the letters “TR” on the sidewall.

Tubeless ready tires must be mounted to tubeless compatible rims and require the use of a liquid sealant to maintain pressure. Liquid sealants have the added benefit of sealing small punctures. Be sure to check your sealant regularly and refresh as needed as it will dry out over time.

Threads Per Inch (TPI)

The number of threads that cross through one square inch of a single ply of the tire’s casing. Lower TPI (ex. 60 TPI) gives better puncture, cut and abrasion resistance but is heavier. Higher TPI (ex. 120 TPI) conforms better to the terrain, offering a smoother, more comfortable ride while reducing the weight of the tire. The trade off being higher TPI casings are more fragile compared to lower TPI casings.

EXO

EXO is a cut- and abrasion-resistant material added to the sidewalls of many Maxxis mountain bike and gravel tires. This densely woven fabric is lightweight and highly flexible, ensuring that the performance of the tire remains unaffected. Choose EXO Protection for enhanced durability for gravel, XC, and light-duty trail riding.

MaxxSpeed

The new MaxxSpeed (2023) is our top-shelf rubber compound for XC racing. It’s a high-silica content compound which reduces rolling resistance while also enhancing wet traction. Compared to the previous 3C MaxxSpeed, the new compound has approximately 25% less rolling resistance in a lab setting (using the same tread pattern, construction, and tire pressure). In a real world setting, our testing shows the new compound can save up to a minute over the course of a 90-minute race.
