RockShox ZEB Charger 3.1 RC2 Suspension Fork

Yes, this fork is fully compatible with electric mountain bikes. Its robust 38mm chassis is designed to handle the additional weight and torque demands typical of modern e-MTB setups.

ButterCups are small rubber pucks integrated into the damper and air spring shafts. They are designed to absorb high-frequency vibrations, effectively blocking about 20% of trail chatter before it reaches your hands, which helps reduce arm fatigue on long descents.

The Charger 3.1 damper features an expanded damping range, giving you more usable adjustment clicks for both high-speed and low-speed compression. This allows for a more precise setup, letting you tune the fork to be more open for better traction or firmer for increased support.

The ZEB platform is designed around specific travel configurations. While the air spring can sometimes be swapped to change travel, this specific model comes set at 180mm, which is optimized for aggressive enduro riding.

The ultra-low friction SKF wiper seals are designed to keep dirt out and oil in, providing a smoother feel over the life of the fork. Like any high-performance suspension, you should still perform regular lower-leg service intervals to maintain that smooth action and protect the stanchions.

This fork uses a 1.5-inch tapered steerer tube and a 15x110mm Boost thru-axle, which are standard for most modern enduro bikes. You should verify that your frame is designed for a 29-inch wheel and a 180mm travel fork to ensure the geometry remains balanced.
