Why We Like The ZEB Ultimate Charger 3 RC2 29in Boost Fork

The ZEB Ultimate Charger 3 RC2 Fork is the premier long-travel enduro fork from RockShox—and quite frankly one of the most capable suspension products we’re utilizing on our favorite builds. Designed for enduro and freeride, it’s revamped with an updated Charger 3 Damper and DebonAir+ Spring to further refine this 38mm stanchion fork. Other key updates include a stronger, redesigned chassis and a built-in pressure relief valve to release unwanted air that can build in the lower leg over time from altitude and temperature changes.

When it comes to ride feel, the updated Zeb Ultimate provides the same supportiveness that the previous Zeb did in high-speed corners and chunky terrain thanks to the beefy 38mm stanchions. What feels new is the small bump sensitivity and tracking ability that RockShox attributes to their new ButterCups which absorb high-frequency trail chatter from things like braking bumps and loose over hard conditions. This is also the main riding advantage that the new bushings and Maxima Suspension Lube are intended to address. The next main on-trail advantage of this fork has to do with the updated Charger 3 damper, which utilizes a completely new Internal Floating Piston design that’s intended to make compression and rebound adjustments completely independent from one another. This allows us to make adjustments that truly only affect one performance characteristic of the fork feel and effectively fine-tune our ride.

Plush Long Travel

I've put it through the wringer
Size Bought:
190mm 29"

My only complaint is to get mid stroke support and even be close to being able to bottom it out, you must get a RUNT or some other aftermarket fix for not having a H&L pressure positive air. Add $250 to whatever price you pay. Regardless. Waaaay better than a 38 unless you're at EWS speeds

Improved Damper

I've put it through the wringer
Size Bought:

Nice upgrade for my eMTB from the original Zeb Select+ with the charger 2 damper. New damper is much better on the small bumps and chatter but progressive and burly enough for the big stuff.
