The RockShox ZEB Ultimate Flight Attendant is a heavy-duty, long-travel (170mm) suspension fork designed for Enduro racing and aggressive E-MTB riding. Built around a stiff 38mm chassis, its defining feature is the integrated Flight Attendant electronic ecosystem.
Instead of manually flipping lockout or compression switches, the fork uses an onboard module and a suite of wireless sensors to read terrain and rider inputs in real-time. It automatically toggles the damper between Open, Pedal, and Firm positions, maximizing pedaling efficiency on climbs and instantly opening up for technical descents.
Key Technical Features
- Flight Attendant Automatic Damping: An electronic module continuously analyzes riding metrics to switch compression states instantly, removing suspension complexity for the rider.
- Charger 3.1 Damper: An updated, descent-focused damper featuring a refined compression range to maintain traction over unpredictable terrain.
- ButterCups Technology: Small elastomer pucks housed at the base of the fork internals. They block up to 20% of high-frequency "trail chatter" (like gravel and small roots), which significantly reduces hand and arm fatigue (arm pump) on long descents.
- DebonAir+ Spring: Tuned to sit higher in its travel compared to previous generations, preventing the fork from diving excessively on steep gradients.
Technical Specifications

Compatibility & Fitment Notes
- Brake Rotors: This fork has a 200mm minimum rotor size requirement. Standard 180mm rotors will not fit without a larger caliper adapter. The maximum supported rotor is 220mm.
- Hub Compatibility: Includes bolt-in torque cap adapters, allowing it to work seamlessly with both standard hub end caps and oversized SRAM Torque Caps.
- E-Bike Status: Fully E-Bike approved, featuring a robust forged hollow aluminum crown and a high maximum system weight limit (bike + rider + gear).
- Mudguard: Includes a short, bolt-on RockShox fender.
Frequently Asked Questions
Q: Do I need other Flight Attendant components to use this fork?
A: Yes. The Flight Attendant system functions as a wireless ecosystem (via SRAM AXS). To utilize the automatic damping adjustments, it requires paired sensors (such as a Flight Attendant-equipped rear shock and a pedal sensor integrated into the crankset) to provide the algorithm with complete rider data.
Q: Will standard 180mm disc brakes fit this fork?
A: No. Because the ZEB is designed for heavy-duty Enduro and E-MTB use, the direct brake mount is sized for a minimum 200mm rotor.
Q: What do the "ButterCups" actually do?
A: They isolate the damper and air spring shafts from the lower legs using rubber packaging. While the main air spring absorbs large impacts (drops, rocks), ButterCups absorb the tiny, rapid vibrations from the trail surface before they reach your handlebars.
Q: What is included?
A: The fork comes with battery, charger and spare bottomless tokens to customise the feel of the fork.
