SID World Cup 29 Charger DebonAir 100 Boost Fork - 2020

If counting grams is of the utmost importance to you and the podium is your ultimate goal, then free your mind of weight worries with the ultra-lightweight chassis of the RockShox SID World Cup 29 Charger DebonAir 100 Boost Fork with Remote Lockout for a competitive edge. Built to save weight at all costs, the SID World Cup is one of the lightest forks out there, thanks to its 32-millimeter stanchions, carbon fiber crown and steerer, and not to mention its knocked-out magnesium dropouts. In this particular 29-inch model with Boost axle spacing and 100 millimeters of travel, the SID World Cup tips the scales at a paltry 1537 grams, or approximately 3.39 pounds.

Just because it's been constructed to save weight in the name of go-fast efficiency, that doesn't mean RockShox cut corners on adjustability or support over small bumps and mid-sized hits. In fact, the additions of a Charger 2 damper, DebonAir spring, and factory-tuned Dig Valve prove that that's not the case. The design allows you to quickly switch between wide open and fully locked out, as well as dial-in the low-speed compression to your particular racing needs, which can be accomplished without reaching down and flicking the switch thanks to an included OneLoc remote lockout.

DebonAir is one of the top features of the SID World Cup, seeing as it increases the negative air spring volume for better compliance over small bumps and higher levels of traction when you're fighting your way up rock-and root-laden climbs. DebonAir really makes it feel plusher off the top and more sensitive to trail imperfections, but without sacrificing support as you push deeper into the travel, due to the Dig Valve providing just the right amount of control over the fork's mid-stroke support and ability to properly absorb impacts.
