We present to you the new XC mud tread – the Severe. It’s likely you’ve seen the tread in World Cup coverage under the likes of Nino Bec McConnell and Anne Terpstra but now the race-winning Severe is available for retail. It’s a classic narrow-profile mud tire in a 2.25” width with a spiky tread pattern designed to cut through thick mud. The Severe isn’t intended for daily use but for rain races it’s indispensable. With the recent redesign of the Forekaster to trail duty the Severe is the new choice for wet weather XC. The Maxxis Severe is spec’d with our 120 TPI tubeless ready casing and new MaxxSpeed compound. Introducing the All-New MaxxSpeed Compound. An all-new MaxxSpeed compound for the Maxxis cross country XC line. The new MaxxSpeed uses silica as a filler in the rubber polymer creating a compound that performs better across the board compared to the old 3C MaxxSpeed. Racers benefit from reduced rolling resistance and improved wet traction. The use of three different durometers of rubber in a single tire–Maxxis’ 3C technology–set our mountain bike tires apart from the competition over the past two decades. But when it was time to develop a new topshelf XC compound we focused on performance above a specific number of compounds. Maxxis engineers used knowledge gained from the development of our full-silica road racing compound and began testing formulations suited to off-road use.  The New MaxxSpeed Compound: Over 25% lower rolling resistance compared to the previous version Saves a rider up to a minute over the course of a 90-minute XC race Racked up World Cup and World Championship wins over the last few seasons with the likes of Nino Schurter Bec Henderson and Ghost Factory Racing Weight: 29x2.25 - 745g TPI: 120 Bead: Foldable Ply Construction: Single Compound: MaxxSpeed Max PSI: 60 Tech: Tubeless Ready EXO
