Maxxis Aspen St 120tpi Maxxspeed/exo Tubeless 29´´ X 2.25 Mtb Tyre. Gain a competitive edge with the MAXXIS Aspen ST, the ultra-low-profile XC race tire nicknamed the "Fastpen." Engineered for maximum velocity on dry short tracks, it features the new high-silica MaxxSpeed compound, slashing rolling resistance for race-winning speed. The supple 120 TPI casing is reinforced with lightweight EXO protection for cut and abrasion resistance without sacrificing performance. Tubeless-ready for superior traction and puncture resistance, this is your go-to tire when every second on the course counts. The Aspen ST is an ultra-low-profile race tire designed primarily for short track XC use. Sometimes referred to as the Fastpen, this tire is sure to give any racer an edge in dry conditions.Specifications:- Size: 29X2.25- Etrto: 57-622- Tpi: 120- Bead: Foldable- Weight (g): 670- Compound: Maxx Speed- Max Psi: 50- Tech: MaxxSpeed/EXO/TR- Application: Mountain- Rubber: MaxxSpeed- Casing: 120 TPI + EXO (XC Race)- Category: XC Race- Recommended Uses: Dry XC Conditions- Recommendation Installation: Front or rearPerformance Ratings:- Rolling Speed: 5/5- Cornering Control: 2/5- Braking Traction: 2/5Technology: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.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.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.Wide Trail XC (WT XC):- Maxxis recommends using 2.40″ Wide Trail XC tires on 30mm internal rims. The tires are compatible with rims as narrow as 25mm, but we do not recommend exceeding 30mm wide. tradeinn Bikeinn
