ZEB B1 Ultimate Charger 3.2 RC2 27.5in Boost Fork

What Our Gearhead® Experts Are Saying:

"I ran the ZEB B1 back to back with a previous-generation fork on the same trail, and the difference in the Charger 3.2 RC2 damper was immediately noticeable. The high-speed compression tune felt more precise and matched perfectly with the LinearXL spring rate, so the fork tracked the ground without blowing through travel. For riders building a serious enduro or freeride rig on a 27.5in platform, this fork is the right foundation."

When you're putting together a dedicated enduro or freeride build around a 27.5in wheel, the fork is the first decision and the one everything else flows from. The RockShox ZEB B1 Ultimate Charger 3.2 RC2 27.5in Boost Fork brings 150mm of travel engineered specifically for high-consequence, high-speed descending, with the damper and spring technology to back it up on the rowdiest terrain in your rotation.

At the core of the ZEB B1 is the LinearXL air spring, which provides a consistent, progressive feel throughout the entire stroke. Paired with Adjustable Bottom Out, it gives riders precise end-stroke control to prevent harsh bottom-outs on massive hits without sacrificing mid-stroke sensitivity. The Charger 3.2 RC2 damper features external adjustments for low and high speed compression as well as begin stroke rebound, with new rebound and compression tunes engineered specifically to complement the LinearXL spring. ButterWagonTech ensures a constant oil supply to the bushings throughout the full service interval, and ButterCups technology blocks 20% of high-frequency vibration before it reaches your hands. The 38mm aluminum stanchions paired with magnesium lower legs provide a stiff, laterally precise chassis.

Compatibility specs are built for modern aggressive builds. The tapered 1-1/8in to 1.5in aluminum steerer pairs with current enduro and freeride headsets, and the 15x110mm Boost thru-axle interface provides maximum front-end stiffness. Maximum tire clearance of 2.93in (74.5mm) and a 220mm max rotor size leave plenty of room for aggressive tire and brake setups. e-Bike approval means this fork is a viable choice for full-power builds as well.

The ZEB B1 Ultimate Charger 3.2 RC2 27.5in Boost Fork is the right spec for riders who prioritize descending performance above all else and want a proven, adjustable platform they can tune to match their riding style and local terrain.
