ZEB Ultimate Red Charger3.2 RC2 B1 29" 44mm OS

The RockShox ZEB Ultimate is built for the most extreme terrain, from steep double-black descents to full freeride lines and aggressive enduro riding. Designed around a proven 38 mm chassis, it combines the latest Charger 3.2 RC2 damper with the new LinearXL air spring to deliver unmatched control, consistency, and composure when pushing limits. The Charger 3.2 RC2 damper features independent high- and low-speed compression adjustment with updated compression and rebound tunes matched to the LinearXL spring. The revised system delivers a quieter, more controlled ride feel with improved mid-stroke support and reduced harshness, while the numbered adjuster layout makes setup simple and repeatable. The LinearXL air spring provides a coil-like ride character, offering supple small-bump sensitivity, strong mid-stroke support, and controlled end-stroke progression with Adjustable Bottom Out. ButterWagonTech ensures a constant oil supply to the bushings, reducing friction and maintaining smooth performance across the full service interval. Combined with ButterCups technology, which reduces high-frequency trail vibration, the ZEB Ultimate delivers a planted and fatigue-reducing ride feel.
