When you’re on the hunt for cross-country podiums, the SID is like a blowgun. Ultra-light and compact, but delivers a deadly blow. Its supremely svelte design shaves every unnecessary ounce off to help you win the battle against gravity and fatigue, while its innovative technologies defy the laws of physics, giving you the stiffness, unparalleled plushness and control you’d only expect from a heavier fork. Happy hunting.

With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 and X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive trail and enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" and 29" wheels as a possible weak link. Which is why SRAM has developed an open standard with Boost compatible components for SRAM drivetrain, hubs and RockShox forks.

Bottomless Tokens

Bottomless Tokens allow riders to easily custom tune their RockShox fork’s air-spring performance to best match their own 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 percent of their fork’s travel.

  • Black bottomless tokens are compatible with the following Solo Air forks: RS-1 SID, Reba, Bluto, Revelation.
  • Grey bottomless tokens are compatible with the following Solo Air forks: Pike, Lyrik, Yari, Pike DJ, BoXXer.
  • Dark red bottomless tokens are compatible with the following Dual Position Air forks: Pike, Lyrik, Yari.

Dig Valve

RockShox has redesigned the rebound piston to accommodate the Dig Valve, which provides the optimal level of control for both low and high speed compression, carefully controlling the oil flow to provide the rider with the right amount of support and impact absorption. The piston redesign allows the use of Rapid Recovery, a rebound tune that allows the shock to recover faster between consecutive bumps, for greater traction and a more controlled ride.

Maxle Lite™

Who obsesses over the weight of their wheel axles? It’s ridiculous, right? It’s just a rod of metal bolting the wheels to your bike. But then again, Maxle Lite is a nifty thru axle system that makes your bike both lighter and stiffer. And less weight makes it easier to get your bike to do what you want. Especially when you don’t need to bring tools to remove it, front or rear. And that extra stiffness gives you the precision to hit your lines no matter how burly. So maybe that obsession isn’t so ridiculous after all. Now available in 20 x 110mm and 15 x 100mm sizes.

Maxle Stealth

Who knew we could make a thru axle disappear? The new Maxle Stealth offers a light, low profile alternative to Maxle Lite and Maxle Ultimate.

Motion Control™

Imagine riding on the moon. Rolling hills, crushed rock blasted out of craters… craters. There’s no gravity so you wouldn’t even need a chairlift. Unfortunately you can’t ride on the moon. There’s lots of gnarly terrain on earth. But, earth has gravity so you’ll need suspension that climbs as well as it descends. With our Motion Control damper technology you’ll do just that. You can’t ride on the moon, but with Motion Control you can make gravity your bitch.

The new OneLoc remote provides total control over your suspension at your fingertips.The increased leverage at the bar, translate in a smoother and easier actuation. Its countless mounting options (left and right, below or above the bar, tall or standard clamp) make it an ideal companion for SRAM's drivetrain, brakes and RockShox's Reverb remote.

Power Bulge™

When you need your forearms to be stronger for more control, you bulk them up in the gym. When you need more durability from your fork, bulk them up with our Power Bulge. Other companies just increase the stanchion size adding extra weight. Power Bulge simply reinforces the lower leg to allow for an oversized bushing, increasing stiffness and maximizing your ride. Plus, it’s called Power Bulge.

Rapid Recovery™

Who doesn't want more available wheel travel for successive hits? The Rapid Recovery System allows the shock to recovery faster between consecutive bumps, letting the wheel track the ground with greater precision. This more active suspension system, doesn’t pack up and enables the bike to ride in a higher and softer part of the spring rate.  Rapid Recovery gives the rider access to more available wheel travel, bump after bump, to achieve a smoother and more controlled ride.

Sag Gradients™

Don’t set your sag correctly, and you might as well be hopping onto someone else’s bike. But why bust out plastic clips or rulers to keep your suspension fine-tuned? Our sag gradients are printed right on our fork’s upper tubes and shock damper bodies making perfect suspension setup easy and accurate. So give mom back her plastic clip and ruler.

Solo Air™

Solo Air is like a Buddhist monk. Its enlightened design lets you add air to your forks through a single Schrader valve, filling both the positive and negative air spring chambers simultaneously. So they’re always in perfect equilibrium, like Yin and Yang. Giving you a plush, predictable ride you can set up in seconds, with the lightest weight air spring on the market.

Torque Caps

Strong connections make for strong relationships. This is as true for people as it is for bicycle components. We applied this thinking to Torque Caps. They 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.
