The M9 was designed to be the uncontested king of downhill and enduro. This means keeping you in control when possible and keeping you moving forward when not. Every piece of carbon in the M9 has been carefully placed to serve a purpose – be it lateral stiffness, impact resistance, power transfer, suspension feel, or ride compliance. In addition to a purpose-built full-carbon fiber laminate, the M9 features ENVE’s patent pending Protective Rim Strip technology. This technology reduces pinch flats, absorbs large amounts of energy, and if you ever do experience a cracked rim – the system is designed to create an independent seal between the tire and rim, ensuring that a cracked rim doesn’t equate to flat tire. PROTECTIVE RIM STRIP - GOODBYE TO PINCH FLATS AND INSERTS The ENVE Protective Rim Strip delivers: Unprecedented pinch/snake-bite flat resistance Ability to run lower pressure and improve traction and rolling resistance (Visit our tire pressure page to dial in your best pressure) The option to run lighter weight tires if desired A protective buffer between rim and trail Improved tubeless performance and durability by eliminating the need to tape rims for a tubeless seal Independent tubeless seal that can allow air pressure integrity in the instance the carbon is damaged or cracked Increased width at leading edge dissipates impact energy and prevent pinch flats. Strip material absorbs energy protecting the ultra-lightweight carbon rim structure. Strip completely seals the air chamber, removes the need for tape and maintains pressure should the carbon be damaged. Full carbon laminate tuned for energy absorption and a smooth ride without sacrificing straight line tracking and lateral stiffness performance.
