The Maxxis Ikon is a versatile XC tire designed to perform in a broad range of conditions. With its predictable handling and high rolling speed, the Ikon is also a favorite among our slopestyle athletes. Features:Rubber:- Dual compound (best for dry, hard conditions)- 3C MaxxSpeed (best for XC race use)- MaxxSpeed (2023) (new formulation of our XC race compound)- 3C MaxxTerra (best for mixed conditions)Casings:- 60 TPI + EXO (general XC use)- 120 TPI + EXO (XC race use)- Tubeless Ready specs are denoted with a TR in the tables belowSpecifications:- Size: 27.5X2.20- Etrto: 56-584- Tpi: 120- Bead: Foldable- Weight (g): 680- Compound: Maxxspeed- Max Psi: 60- Tech: MaxxSpeed/EXO/TR- Application: MountainPerformance Ratings:- Rolling Speed: 4/5- Cornering Control: 2/5- Braking Traction: 2.5/5Technology: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.3C MaxxSpeed:- Used primarily in cross country (XC) tires, the two compounds in the outer layer are specially formulated to reduce rolling resistance and optimize treadwear and traction.3C MaxxTerra:- Maxxis' 3C MaxxTerra is an intermediate triple compound configuration used across our mountain tire line. The 3C MaxxTerra compound offers more traction than 3C MaxxSpeed, yet provides better treadwear and less rolling resistance than MaxxGrip, which makes it ideal for trail riding in all conditions.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.
