Climb mountains. Charge descents. SID Ultimate isn’t like other XC forks. It is lighter than ever with a formidable 35mm chassis that holds the line when you’re on the edge. The new Race Day 2 damper features a three-position (3P) compression adjuster—rigid Lock, plush Open, and efficient Pedal positions, all at your fingertips. SID adapts to everything from full-gas cross-country to sporty backcountry loops thanks to a new, higher-volume DebonAir+ spring that’s supple at the top of its travel with tons of tunability.

SID Ultimate 3P

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.

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 Race Day 2 Damper

A new damper built for speed. Our lightest production damper. Ever. Performance packed with a rock-solid lockout to power up climbs and smash through sprint finishes.

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.
