2023 RockShox ZEB ULTIMATE Charger 3

RockShox ZEB ULTIMATE fork is a completely new fork, designed to challenge the limits and tackle the toughest Enduro tracks in the world.

• Pin 15×110 mm Maxle Ultimate.
• New Charger 3 cartridge, which ensures total independence of the high speed (HSC) and low speed (LSC) compression circuits.
• Cartridge with floating piston (IFP, internal floating piston) assisted by a spring to minimize static friction.
• Fluid and constantly oiled compression control mechanism to react with maximum speed.
• All the elements of the Charger 3 are made of metal and the hydraulic circuit can be disassembled and overhauled if necessary.
• Two coaxial commands: the larger one is for high speeds and the smaller one (i.e. the top one) is for low compression speeds.
• New number of clicks of the two registers: 14 for the low and 4 for the high, fewer, but much more easily noticeable, especially easier to manage.
• Updated Buttercups, featured on all Ultimate models of Pike, Lyrik and Zeb forks.
• The buttercups are located in the lower part of the fork, both on the left and on the right, and are two rubber elements that first receive the inputs that the front wheel transfers to the fork. These two elements are able to reduce low-amplitude and high-frequency vibrations reaching the handlebar by 20%.
• Sliding bushings 53% longer than the previous ones, to reduce friction.
• Rear relief valves to eliminate the excess pressure that is created inside the fork in the event of a change in altitude or temperature.
• 38mm stems.
• Tapered head tube 1 1/8 “- 1.5.
• New Debonair + system provides for a revised length of the recess (ie the channel through which the air passes to balance the pressure between the positive and negative chambers).
• Upper buffer and volume of positive and negative chambers revised to improve the behavior of the air cartridge.
• Maxima Plush cushioning oil for less friction and better response.
• Postmount caliper attachment 200mm.
• Maximum disc size allowed 220 mm.
• Maximum tire width: 81 mm – 29 “x 2.80”.
• Also compatible with 27.5 “up to 3.00”.
• Offset 44mm.
• Weight 2350gr.
• Color: gray.
