The RockShox ZEB Ultimate Charger 3. 1 RC2 27. 5in Boost Fork was born to handle sketchy descents and big hits with grace and composure. Featuring a new charger 3. 1 RC2 damper, the new Zeb gives us a broader range of adjustments with high and low-speed compression and low-speed rebound adjustments. Massive 38mm stanchions combined with RockShox's ButterCups plow through rough trails, reduce trail vibrations, and make for a smoother ride. The Zeb uses Maxima Plush Dynamix Suspension Lube for reduced friction and better performance and has SKS ultra-low friction wiper seals for improved performance and durability. This fork includes a RockShox short fender to keep our bike cleaner and two bottom-out tokens so we can tune our end stroke to our preference.
