Designed specifically for aggressive trail, enduro, and downhill riding—including long-travel e-bikes—this tire excels in demanding conditions where traction and predictability are critical. Built with an E-rating for gravity performance, the Assegai ensures reliable handling even at high speeds and under heavy load. Whether navigating technical descents, steep climbs, or loose terrain, this tire provides consistent braking and cornering confidence, making it a trusted choice for serious riders pushing the limits of modern mountain biking.

Key Features

• Greg Minnaar Signature Tread Design: Co-designed with three-time World Champion Greg Minnaar, the Assegai’s tread pattern offers tenacious and predictable grip throughout the entire contact patch, regardless of lean angle—ideal for aggressive riding styles.
• 3C MaxxGrip Compound: Utilizes Maxxis’ stickiest, slow-rebounding rubber compound, optimized for maximum traction. This premium formulation is used by elite athletes in the World Cup Downhill and Enduro World Series and is now available across multiple casing options to suit various riding demands.
• EXO+ Protection: An enhanced version of EXO durability, featuring a butyl insert around the bead for added bead stability and resistance to pinch flats. Ideal for rocky, rooty trails and compatible with lighter e-bike applications, offering a balance of strength and ride comfort.
• E25 Rating: Certified for use on light-duty e-bikes with assistance up to 16.1 MPH, ensuring compatibility with a wide range of e-mountain bikes while maintaining performance standards.
• Wide Trail (WT) Optimization: The tread layout and profile are tailored for today’s wider rims (19mm–35mm internal width). A 30mm internal width rim delivers optimal performance, but WT sizing ensures versatility across different frame and wheel setups.

Benefits & Use Cases

The Maxxis Assegai is engineered for riders who demand uncompromising grip and durability on challenging terrain. Its wide trail optimization makes it ideal for modern e-bikes with longer travel forks and slacker geometry, where control at speed is paramount. The 3C MaxxGrip compound provides superior braking and cornering traction on loose dirt, hardpack, wet rock, or muddy trails—ensuring confidence whether descending at full tilt or climbing steep gradients under motor assist.

With EXO+ protection, the tire resists cuts and abrasions from roots and rocks common in trail and enduro settings, while the butyl bead insert enhances stability during high-pressure runs or heavy loads typical of e-bike usage. The E25 rating confirms its suitability for e-bikes with throttle or pedal-assist systems capped at 16.1 MPH, making it a safe and effective choice for lighter-duty electric mountain bikes.

This tire shines in environments requiring precise feedback and responsive handling, such as tight switchbacks, rocky descents, or technical singletrack. Its balanced construction supports both aggressive cornering and strong braking performance, reducing the risk of sliding or loss of control. Whether you’re tackling a local trail park, competing in enduro events, or exploring remote backcountry routes on your e-bike, the Assegai offers the reliability and performance needed to ride harder and faster.
