Maxxis' all-purpose road race tire receives a refresh for 2021 with a new lighter weight casing, upgraded puncture protection, and a revised tread pattern. The result is a lighter, faster, and more durable High Road.Features:- 170 TPI casing- HYPR compound- Pro level competition tire- ZK puncture protectionSpecifications:- Size: 700X25C- Etrto: 25-622- Tpi: 150- Bead: FOLDABLE- Weight (g): 265- Compound: HYPR-S- Max Psi: 85- Tech: HYPR/K2/TR- Application: ROADTechnology:HYPR Compound:- HYPR is a full-silica compound and our best-performing compound to date. Compared to our previous road racing compound, HYPR has 16% less rolling resistance with 23% better grip in wet conditions. Impressively, HYPR decreases rolling resistance and increases traction, all while keeping durability equal to our previous rubber compounds.ZK:- ZK is our next generation puncture protection material that is lighter, more flexible, and stronger than previous materials such as K2. Maxxis typically uses ZK as a breaker layer, situated underneath the tread in the middle of the tire.Tubeless Ready:- Maxxis Tubeless Ready (TR) tires offer better traction, lower rolling resistance, and fewer flats by eliminating the inner tube. Run lower pressures for improved grip and control. Look for the TR marking on the sidewall.- Installation Note: Must be used with tubeless-compatible rims and liquid sealant to maintain air pressure and seal small punctures. Check and refresh sealant regularly as it dries over time.- Important: Use sealant only in tubeless road, tubular, or tubeless ready tires. Using it in other Maxxis models voids the warranty.
