Welcome to the Mavic website

Designed to transform your electric mountain bike into a trail rocket, the E-Crosstrail SL Carbon 29 wheels rely on a dynamic design and exceptional strength to deliver a unique riding experience, while reducing battery consumption. Magic from Mavic.

Thanks to lightweight carbon rims that make no concessions to strength, the E-Crosstrail SL Carbon 29 considerably reduce inertia for better acceleration and increased control. The steel spokes, designed by our teams at the foot of the French Alps, are also lighter, improving vertical compliance and control for greater confidence on uneven terrain. Finally, the new Infinity hub with 28 steel spokes maintains high lateral stiffness for optimal stability when cornering. You'll love dancing on the trails.

Designed to handle the high torque of e-bike motors, this robust, high-performance wheel is fitted with a wide 30mm rim (internal), which adds extra rigidity and precision when cornering, allowing you to negotiate corners with absolute confidence.

Like all Mavic wheels, the E-Crosstrail SL Carbon 29 has been designed with durability and repairability at the top of our priorities, with an ultra-reliable ID360 freewheel and tubeless system for easy tire mounting, all to save time and energy when servicing your wheels. For extra peace of mind, the E-Crosstrail SL Carbon 29 wheels come with two spare spokes per wheel, so you can go out and make trouble without having to start all over again in the workshop.

The E-Crosstrail SL Carbon 29 wheels are an unrivaled choice for optimizing the performance of your electric mountain bike, with dynamic handling and unfailing robustness. Science moves forward, and so do your wheels.

Key technology

Efficiency RigidityInstant Drive 360 freewheel technology
The new Instant Drive 360 freewheel system is super light and efficient. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
Efficiency RigidityUST tubeless technology
Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats.
Safety ReliabilityInfinity hub design
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution.
Safety ReliabilityQRM Auto bearing preload technology
Qualité de Roulements Mavic Auto. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
