Engineered for the absolute limits of gravity riding, the all NEW 2027 RockShox ZEB Ultimate (FS-ZEB-ULT-B1) dominates steep double-blacks and massive freeride hits while retaining the efficiency to earn the pedal back to the top. Its revolutionary LinearXL air spring utilizes expanded lower-leg volume to eliminate harsh, speed-sensitive ramping, delivering a hyper-predictable, coil-like plunge. To manage catastrophic impacts, a precise Adjustable Bottom Out (ABO) system grants you total end-stroke authority. Exclusive to the Ultimate tier, SRAM proprietary ButterWagonTech features a matrix of stanchion divots that actively pull high-density oil into the bushings with every millimeter of travel, slashing static friction by up to 24%. The fiercely independent circuits on the new Charger 3.2 damper eliminate cross-talk for surgical tuning, while integrated ButterCups mute high-frequency chatter by up to 20% to drastically reduce arm pump. When the trail descends into total chaos, the ZEB provides the unflinching composure you need to lock onto your line and absolutely conquer it.
