Rock Shox Zeb Ultimate RC2 Debon Air Charger 3.1 29" Boost tapered rake 44 mm frk

Built for the best riders, ridden on the hardest tracks, ZEB Ultimate rules the world’s toughest enduros

Equipped with the new Charger 3.1 RC2 damper, ZEB gives riders exceptional adjustability for the right balance of comfort, control, and speed. Alongside this flagship damper, the stout 38mm chassis rides on vibration-killing ButterCups and a DebonAir+ spring. The technology you need for the fastest split times, the style you want on the start line: This is ZEB. To meet the demands of the world’s best riders, Charger 3.1 is a brilliant evolution of the proven damper platform. With increased damping range and High Speed Compression, Low Speed Compression, and Low Speed Rebound adjustments, Charger 3.1 smooths out the roughest trails.

Features

• Charger 3.1 RC2’s adjustment range is broader—with less compression damping in the LSC open position and additional support in the HSC closed position, you get the traction, control, and comfort you need to charge dicey lines all day
• Ever on the quest to eliminate friction, a new bushing package further reduces friction with an updated process at the factory level to give riders a better feel right out of the box
• ButterCups block 20% of high-frequency “trail chatter”. Limiting these vibrations massively reduces hand and arm fatigue leaving you feeling fresh with more control
• DebonAir+ air spring is built to strike the perfect balance of what riders really want: a butterlike small bump feel, increased air volume to add support throughout the travel, and higher overall ride height for more confidence when things get steep
• Maxima Plush Dynamic Suspension Lube reduces friction, lasts longer, and enhances suspension performance ride after ride
• Bolt-in torque cap adapters now included for use with standard hub end caps
• Lightweight machined and anodized crown for premium looks and durability
• Ultra-low friction SKF wiper seals provide long lasting fork performance and improve overall suspension feel
• Short fender compatibility. (RockShox fender included)

Technologies

Bottomless Tokens
Bottomless Tokens allow you to easily custom tune your air-spring performance to best match your riding style and suspension preference. Adding the easy-to-install Bottomless Tokens changes the air-spring curve to resist bottom-out after a big hit, giving aggressive riders the power to attack the trail harder. Removing Bottomless Tokens makes the air-spring curve more linear, enhancing suspension feel for certain types of terrain or trail condition and ensuring riders who are less front-end aggressive benefit from 100% of their fork’s travel.

Boost
BOOST is the standard wheel and drivetrain specification that opens the opportunity for improved frame geometry with shorter chain stays, wider and stiffer suspension pivots, wider range of chainring options, as well as more clearance for bigger tires and wider, stiffer wheels.

Torque Caps
Torque Caps make the bond between hub and fork dropout stronger, with an increased surface area connecting the two. This creates a stronger, stiffer interface, giving you a more responsive front wheel and more control. So you concentrate on the most important connection, the one between your bike and the trail.

Maxima Plush Fluid
Developed with the world's fastest racers, on the world's toughest circuits. Maxima Plush Fluid is designed to protect from suspension wear, reduce friction, and silence damper noise while maintaining a consistent feel in all temperatures.

SKF Seals
Everyone loves a good collaboration, which is why Rock Shox has been working with SKF, the world’s highest-performance seal manufacturer, for over 5 years.  Together Rock Shox’ll provide ultra-low friction wiper seals, less fatigue, and unmatched suspension feel, all while keeping the dirt where it belongs- because no one wants dirt in there.

ButterCups
Low amplitude, vibration reducing material pucks... but Rock Shox likes to call them ButterCups. ButterCups block 20% of unwanted “trail chatter” before it reaches your hands. The gold housings on the end of the damper and air spring hold two rubber pucks that absorb the high frequency vibrations before they travel through the fork and into the handlebar. ButterCups reduce overall hand and arm fatigue and will leave you feeling fresh with more control over the trail.

DebonAir+
DebonAir+ is built to strike the perfect balance of what riders really want: butter-like small bump feel, increased support throughout the travel, and higher overall ride height for more confidence when things get steep.

Charger 3
Scrap everything and start from scratch. It took a fresh set of eyes to produce what became the Charger 3 damper. Let’s see what Rock Shox can do, where Rock Shox can go. The result gives way to a new era of riding, where the decision between adding more damping and sacrificing your hands to a harsh ride doesn’t exist.

Maxima Plush Dynamic Suspension Lube
Maxima Plush Dynamic Suspension Lube reduces friction, lasts longer, and enhances suspension performance ride after ride.
