Evolution of Big Mountain

The evolution of the RUX continues to be a wild and exciting ride. Today’s RUX is bred from the many years of collaboration between our riders across the globe and the SR SUNTOUR team, leading to the development of a world class Downhill and Freeride suspension fork. Tried and true, the RUX’s list of accomplishments grows longer into 2020, with a consistent presence on World Cup Downhill and Red Bull Rampage podiums. Creating the most reliable, durable, and serviceable suspension on the mountain is what drives the evolution of the RUX. For riders seeking the biggest of big mountain lines, the progression of Freeride, or pushing the fastest time down the track, it is essential to ride with the confidence of an extra stiff 38mm stanchion chassis and fully-sealed R2C2 and RC2-PCS dampers. Whether it’s at the home tracks, traveling on a race circuit, hunting down new zones, or just going new places to ride, the ease of performing basic service and maintenance is a pillar of the QSP philosophy that enables riders and mechanics to confidently keep their forks dialed and ready for the next adventure.
