RockShox RS-1 120 29" Fork

The recent progression in bicycle technology can seem rather overwhelming at times, as it seems that standards change on what might be a yearly basis. Just when you thought you finally had a grasp on the latest, greatest bag of tricks, word of a new state of the art component sweeps across the industry like a wildfire. Well here is our fair warning; reading on may cause XCers to lose all feelings of content toward their current suspension fork. The Rockshox RS-1 is one of those game-changing releases that can potentially restore the standards for Cross Country suspension forks. After a ruthless revaluation of material optimization, and every other element that classifies one of the most decorated XC forks in world cup history, the RS-1 ushers in a new cohort approach to XC rider efficiency and capacity.

The inverted design is all new to Rockshox and delivers a new level of ride quality that's simply unachievable through conventional fork designs. The revolutionary chassis design integrates the fork's steerer tube, crown and legs into a single carbon main frame, while a reimagined interface between hub and dropouts, dubbed Predictive Steering, enable an inverted design that's light enough for XC racing, yet stiff enough for trail riding. The large 27mm diameter Torque Tube oversize axle creates an unbreakable bond, locking the lowers in place to maximize torsional stiffness and reduce fork twisting. A wider hub flange spacing results in a stronger, more responsive wheel, while the new Maxle Ultimate completes the connection with a tighter, stronger clamping force than you'd get from a quick release.

Through the new Accelerator Damper the RS-1 features a firmer lockout for improved energy transfer and acceleration. The Rapid Recovery system allows the shock to recover faster between repetitive bumps, keeping the fork riding in the plushest part of the travel for a smoother ride, while the Dig Valve compression tune was spawned to carefully manage the oil flow to provide the perfect amount of support during successive hits and intense braking. To shave unnecessary weight, the circuit is housed in a sealed cartridge, eliminating material redundancies. To sweeten up the RS-1, the XLoc Sprint hydraulic lockout offers completely sealed and dependable lockout control through the click of a highly accessible button. Simply press on to unlock, and press again to lock.

Other features include: Air Guides printed on the fork to help you set up your suspension in seconds instead of minutes, Sag Gradients printed on the upper tubes allowing easy and accurate setup, and Solo Air technology that lets you add air to your fork through a single Schrader valve, filling both the positive and negative air spring chambers simultaneously for perfect equilibrium.
