Rockshox Black Zeb Ultimate Charger Boost 29" Fork Size 3.2

RockShox

The RockShox ZEB Ultimate Charger 3.2 29" B1 Fork is a long-travel enduro and freeride suspension fork built for high-speed control, precise handling, and consistent performance on demanding terrain. A stiff 38 mm chassis provides front-end stability through rough trails, while the Charger 3.2 RC2 damper with ButterCups reduces vibration and improves control. The LinearXL air spring delivers a smooth, coil-like feel with strong mid-stroke support, and Adjustable Bottom Out allows fine-tuning for heavy impacts. ButterWagonTech ensures constant lubrication to maintain smooth performance over time.Key Features and Benefits:38mm chassis construction: The oversized upper tubes increase torsional stiffness and steering precision. This keeps the front end stable under heavy loads and high-speed impacts, resulting in more accurate line control on technical terrain.LinearXL air spring: This air spring design creates a coil-like feel with a supple initial stroke and strong mid-stroke support. It improves traction on small bumps while maintaining support through compressions, leading to better control across varied terrain.Adjustable Bottom Out (ABO): External bottom-out adjustment lets you fine-tune end-stroke progression. This helps prevent harsh bottom-outs on big hits, resulting in more consistent performance on aggressive descents.Charger 3.2 RC2 damper: Independent high- and low-speed compression adjustment allows precise suspension tuning. This gives better control over fork behaviour in different conditions, resulting in improved handling and responsiveness.ButterCups technology: Integrated vibration-damping units reduce high-frequency trail chatter. This lowers hand and arm fatigue, allowing you to maintain control for longer periods.ButterWagonTech lubrication system: Continuous oil flow to the bushings reduces internal friction and wear. This maintains smooth suspension movement over time, resulting in consistent performance between services.SKF low-friction wiper seals: High-quality seals minimise friction while keeping contaminants out. This improves small bump sensitivity and extends service life, resulting in smoother and more reliable performance.Maxima 920 suspension fluid: A dedicated low-friction fluid reduces internal resistance within the fork. This ensures consistent damping performance, resulting in stable behaviour across long descents.This fork is built to maintain control when speeds increase and terrain becomes more unpredictable. The combination of a stiff chassis, controlled damping, and reduced vibration keeps the front wheel tracking accurately. Adjustable Bottom Out and the LinearXL spring allow you to tune support for aggressive riding without losing sensitivity. This balance of control and consistency helps you stay composed on repeated impacts and long descents.With its advanced damping control, vibration reduction, and tunable spring system, this fork is designed to perform under pressure. It offers the adjustment range and durability needed for demanding riding, making it a strong choice for riders pushing harder lines.Specification:Wheel size: 29"Travel: 150mm, 160mm, 170mm, 180mmDamper type: Charger 3.2 RC2 with ButterCupsFork offset: 44mm (27.5"), 44mm (29")Colour: Electric Red - Gloss, Gloss BlackAxle: 15×110 mm BOOST TCUpper tube: 38mm aluminiumVolume reducer: 0/3 tokens, 0/4 tokens, 1/4 tokens, 1/5 tokensSpring: Linear XL with ButterCupsCrown OD: 59mmBottom out: Externally Adjustable Bottom OutCompression tune: C5Rebound tune: R55
