The ZEB B1 Ultimate Charger 3.2 RC2 27.5in Boost Fork was born for the steep, rowdy, and untamed
What Our Gearhead® Experts Are Saying:
"I threw the ZEB B1 on my enduro rig ahead of a trip to some of the steepest terrain I'd ridden all season. The LinearXL air spring gave me that smooth, consistent feel from the very first stroke all the way through the hardest hits, and I never once felt like I was fighting the fork. The Charger 3.2 damper kept everything dialed on the way down, letting me stay focused on picking my line instead of managing my bike."
Some trails don't ask nicely. The ZEB B1 Ultimate Charger 3.2 RC2 27.5in Boost Fork from RockShox was purpose-built for the kind of terrain that demands full commitment, whether that's a chunky double-black descent, a massive freeride feature, or a technical line that sends most riders around the long way. When the trail gets rowdy, this fork gets to work.
The Charger 3.2 RC2 damper delivers virtually silent, precise control with external adjustments for both low and high speed compression as well as begin stroke rebound, so you can tune your ride to the exact trail underfoot. ButterCups technology absorbs high-frequency trail chatter at the source, taking a 20% bite out of the vibration that wears down your hands and arms over a long day in the saddle. Pair that with the Adjustable Bottom Out control and the LinearXL air spring, and you have a fork that stays composed through the biggest hits while still being active and supple when the trail demands it.
