The Mavic E-Crosstrail SL 29 wheel builds its Infinity hub specifically to handle the constant torque and power delivery of an E-bike motor, not just pedal input. The reinforced hub body holds tension without flexing under sustained load, so power reaches the tire the same way on lap ten as it does on lap one. A symmetric spoke build front and rear, 28 spokes in a 3-cross pattern on both wheels, keeps that load distributed evenly across the wheel. What Our Gearhead(R) Experts Are Saying:"I've run this wheel on an E-bike through a full season of climbs where the motor never lets the wheel coast, and it still holds true. Sustained power under load is a different kind of stress than a single hard pedal stroke, and this wheel doesn't show it."
