RockShox SID SL Ultimate 3P Boost 2023 Fork

Cross-country purists… we see you. You’re why SID SL Ultimate is the lightest XC fork on the trail. But weight is meaningless without world-class performance and durability. SID SL features a new Charger Race Day 2 Damper with three-position (3P) compression damping—rigid Lock, plush Open, and efficient Pedal positions, on demand for every inch of the race course.

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 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.
