Technology

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.

DebonAir

A lightweight, highly tune-able air spring designed to offer a coil-like consistent feel throughout the travel –
effortlessly soaking up the smallest hits and tracking the slightest changes in the terrain.

Sag Gradients

Measurement gradients indicating the current sag and travel settings are conveniently located on the upper tubes so
that you always know how much travel you are running. You won’t find this anywhere else but RockShox.

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.

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.

Charger RC Damper

Charger RC features an extruded bladder design that allows you to adjust low speed compression anywhere between fully
open to firm.

SKF Seals

Everyone loves a good collaboration, which is why we’ve been working with SKF, the world’s highest-performance seal
manufacturer, for over 5 years. Together we’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.
