Power BulgePower Bulge simply reinforces the lower leg to allow for an oversized bushing, increasing stiffness and maximizing your ride Rapid RecoveryThe Rapid Recovery System allows the shock to recover 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 DebonAirIt's ok to be soft. DebonAir is not ashamed to give way under the weakest push. In fact, it makes RockShox forks and rear shocks that are equipped with it plusher than ever, right from the start. It might seem a weakness, until you take DebonAir to the trail. The connection between your bike and the terrain will be seamless, as your DebonAir equipped suspension absorbs every little hit without any harsh feeling on your body. It's designed to be so soft, you can push way harder.. Bottomless TokensBottomless 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.
