RockShox's RS1 ACS Solo Air Forks design takes its inspiration from the classic RS-1 fork but features a unique, modern construction for increased steering precision, strength and durability.
In a never seen before chassis design, RockShox has integrated the upper legs, crown and steerer tube together into a single carbon mainframe. The result of this is unrivalled handling, rigidity and a very low overall weight.
Of course, precise handling and strength aren’t the only things you look for with a top-end suspension fork. This is why RockShox included its “Accelerator Damper”, which ensures optimum control and the ability to maintain speed over rough terrain due to its excellent small bump sensitivity.
To further enhance the steering precision, the RS-1 ACS Solo Air forks boast “Predictive Steering” technology, which improves the connection between the forks dropouts and the hub. This means these forks are stiff enough for aggressive trail riding and light enough for long distance cross country riding.
Air Guides: RockShox print Air Guides on all of their air-sprung forks. Maybe not a technological feat, but it will help you set up your suspension in seconds instead of minutes. And more time on your bike equals more chances to earn King of the Mountain on your favourite trail. Maybe they are a technological feat.
Maxle Ultimate: Basic things like axles are often the easiest to overlook. Put one hand on the Maxle Ultimate, though, and you'll be glad they paid serious attention to the finer details. Because one hand is all it takes to remove or install the Maxle Ultimate. Personalised lever placement is accomplished completely without the use of tools. Available for both front and rear, Maxle Ultimate is the easiest-to-operate axle system in the world. No tools, no worries, so you can concentrate on the trail ahead.
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.
Accelerator Damper: RockShox re-evaluated how XC athletes produce efficient power and navigate course conditions while fatigued. They then created a firmer lockout for moments of maximum sprint efficiency and added the Rapid Recovery system to keep the fork riding high, in the plushest part of the travel. Then, air was eliminated from the damper circuit ensuring absolute consistency. The Dig Valve compression tune was created to manage diving during successive hits and heavy braking. RockShox also eliminated material redundancies by housing the circuit in a sealed cartridge, reducing weight. The Accelerator Damper crystalizes the performance of RS-1 by helping riders turn every pedal stroke into acceleration towards the top step of the podium.
Predictive Steering: Unique fork, axle and compression technologies combine at the core of Predictive Steering. Fork twisting is reduced thanks to the large-diameter TORQUE TUBE axle that creates an unbreakable bond, locking the lowers in place and maximizing torsional stiffness. A wider hub flange spacing results in a stronger, more responsive wheel. The new Maxle Ultimate completes the connection with a tighter, stronger clamping force than you'd expect with a quick release compression system. Compatible with the SRAM Predictive Steering hubs and the RISE XX, RISE 60 and ROAM 50 29" Wheels, and featured on RockShox RS-1.
RockShox was one of the first producers of bicycle suspension forks and have now become the world leader in the design and manufacturing of high performance suspension products for the bicycle industry. In 1989 RockShox Inc. was founded by Paul Turner and Steve Simons. Rock Shox launched with 10 front suspension forks and three rear shocks, with the brand names such as Boxxer, Deluxe, Indy, Jett, Judy, Mag, Quadra, Ruby and SID. RockShox’s founder Paul Turner, raced motorcycles in his teen years during the 1970s and went on to found an aftermarket engine parts company in 1977 at the age of 18. Turner then went to work for Honda Motor Company, as their factory motocross team mechanic, an opportunity which provided Turner with experience working with the top racers in the field, as well as suspension designers and other motocross industry leaders. In Febuary 2002, RockShox was acquired by industry leader SRAM who hope to take the brand onto another level.
