RockShox ZEB Ultimate: The Benchmark Big-Mountain Fork
ZEB Ultimate is the fork most aggressive riders end up comparing everything else to. It’s stiff, controlled and incredibly predictable when things get steep, fast and rough.
This latest version brings improved small bump sensitivity, better mid-stroke support and more tunability, making it easier than ever to dial in exactly how you want your bike to feel.
No electronics, no distractions, just top-tier suspension performance.
Charger 3.2 Damper – Precise, Tunable Control
The Charger 3.2 damper gives you independent high and low-speed compression adjustment, along with refined rebound control.
It’s intuitive to set up and gives a huge range of adjustment depending on how and where you ride.
Linear XL Air Spring : Smooth, Supportive, Predictable
RockShox have refined the air spring to feel more coil-like through the travel.
It stays composed under load, offers excellent mid-stroke support, and resists harsh bottom-outs with Adjustable Bottom Out.
ButterCups : Trail Chatter, Dialled Down
ButterCups reduce high-frequency vibration through the fork, helping reduce fatigue and keep your hands fresher on longer descents.
It’s one of those features you don’t notice, until you ride without it.
Built for Proper Riding
With a stiff 38mm chassis and options up to 180mm travel, ZEB Ultimate is built for enduro racing, bike park laps and aggressive trail riding.
It’s a fork that holds lines when things get messy.
ZEB In a nut shell
ZEB Ultimate is all about control and confidence. If you want a fork that you can push hard, trust completely and fine-tune to perfection, this is the one.

Everything Revolves Around the Air Spring
Damper performance has defined the conversation in mountain biking, but without the best air spring, the best damper isn’t. LinearXL is a whole fork approach to air spring design, reducing the speed-sensitivity of the air spring—delivering predictable position-sensitive control
LinearXL Linearity Breeds Capability
LinearXL provides a position-sensitive linear curve. That means as you move through the travel, the rate at which the fork increases force never changes—delivering predictability. It’s supple off the top, supportive through the mid-stroke, and backed by an adjustable bottom-out system so you can smash to the end-stroke with confidence and aggression. LinearXL’s whole fork approach also accounts for captured air in the lower legs, eliminating inconsistent speed sensitivity.
Independent Bottom Out Control. On-Trail Adjustability
To give riders a truly predictable rider feel,LinearXL demanded innovation with bottom-outcontrol. Adjustable Bottom Out (ABO) lets youdial in exactly how much bottom-out supportyou want, while keeping the rest of the strokeconsistent and predictable. Turning what waspreviously impossible for an air spring intoincredible-feeling reality
LinearXL Air Annex
The AirAnnex on ZEB’s lower leg increases the lower leg air volume, which reduces the air-spring progressivity and speed-sensitivity inherent to traditional lower leg designs. Transforming what was previously uncontrollable speed-sensitive progression into linear predictability for riders
Stanchions that Breathe
Strategically placed breather holes in the stanchions allow for the lower leg air volume to increase as the fork goes through its travel. A small feature that transforms what was previously uncontrollable speed-sensitive progression into linear predictability for riders.
Charger 3.2 Speed-Sensitive and Silent
Re-tuned for the unique position-sensitivity of LinearXL, Charger 3.2 delivers speed-sensitive control with fully independent High Speed and Low Speed Compression damping. Because a damper should feel and sound incredible. That sound is silence.
ButterWagon Tech : Constant Bushing Lubrication
ButterWagonTech is a proprietary matrix of divots on ZEB stanchions that works to carry (or ‘wagon’) fresh layers of our exclusive, high-density Maxima oil to the bushings with every millimeter of travel. Unparalleled in design and function, ButterWagonTech sets a new benchmark for sensitivity.
Buttercups Vibration Reduction
ButterCups effectively isolate the air spring and damper shafts from chatter, cutting high-frequency vibration by up to 20%. Riders feel the difference, whether smashing up technical terrain on your e-bike or park laps all day. Less arm pump. Less hand fatigue. More fun all day
