When it was time to further develop the XC platform, every element that made up the most victorious XC suspension fork in World Cup history had to be re-tested from the ground up. Ruthless material improvements, a highly efficient, energy-saving lockout and probably the lightest air spring in the world - all designed to keep drivers happy with the successor. The result was rather unexpected. A suspension fork that offers innovative efficiency for XC riders packed in a frame design never seen before in RockShox. RS-1 draws on 25 years of creativity, optimization and the courage to face the biggest technical challenge in mountain bike suspension forks to date: the inverted frame.
