Climb mountains and tackle descents with the new RockShox Sid Ultimate.

The new fork SID Ultimate Race Day is not like other XC forks. It is lighter than ever, with a formidable 35 mm frame that stays true when pushed to the limit. The new Race Day 2 damper features a three-position compression adjuster (3P): Firm Lock, Soft Open, and Efficient Pedal, all within easy reach. The SID adapts to everything, from full-gas cross-country to sporty backcountry loops, thanks to the new higher-volume DebonAir+ spring, which is soft at the beginning of the travel with a wide range of adjustment.

Features

• The new 35 mm frame is the perfect combination of lightness and stiffness for modern XC bikes. Plus, it has been made lighter!
• The new Charger Race Day 2 damper is the lightest on the market. This 3P damper offers three compression positions: Open, Pedal, or Lock.
• The new DebonAir+ provides greater sensitivity to small bumps and adjustable mid-stroke support.
• The new bushing package maximizes bushing overlap for smooth and solid riding.
• The new Maxima Plush dynamic suspension fluid reduces friction, lasts longer, and improves suspension performance, pedal stroke after pedal stroke.
• New arch designed to reduce weight without compromising strength and stiffness.
• New exclusive colors "Blue Crush" and Ultimate High Gloss Black, with the new Pearl White graphic package.
• New Bolt-in adapters for standard hub covers.

Technologies

Bottomless Tokens
Bottomless tokens allow easy adjustment of air spring performance to best suit your riding style and suspension preferences. Adding the easy-to-install Bottomless Tokens changes the air spring curve to resist bottom-out after a hard impact, giving aggressive riders the power to attack the trail harder. Removing the Bottomless Tokens makes the air spring curve more linear, improving suspension feel on certain terrain types or trail conditions and ensuring less aggressive riders get 100% fork travel.

Sag Gradients
Measurement gradients indicating current sag and travel settings are conveniently placed on the upper tubes, so you always know how much travel you are using. You won’t find this anywhere else but RockShox.

BOOST
BOOST is the standard specification for wheels and drivetrain that offers the opportunity to improve frame geometry with shorter chainstays, wider and stiffer suspension axles, a wider range of gearing options, as well as more space for larger tires and wider, stiffer wheels.

Maxima Plush Fluid
Developed with the world’s fastest riders on the world’s toughest circuits. Maxima Plush fluid is designed to protect suspension wear, reduce friction, and silence damper noise, maintaining a consistent feel at all temperatures.

Charger Race Day Damper
A new damper built for speed. The lightest production damper ever. High performance with rock-solid lockout for climbing and sprint finishes.

DebonAir+
DebonAir+ is built to find the perfect balance of what riders want: smooth feel over small bumps, increased support throughout the travel, and a higher overall ride height for more confidence when things get steep.
