Origin
The Helium name has been Ridley's answer to the climbing market since the 2000s. The SLX designation (Super Light Xtra) arrived as Ridley refined the lay-up with 60T high-modulus Toray fibres and F-Steerer integration. It sits above the Helium in the range, targeting grand-tour mountain stages and weight-conscious enthusiasts who want the brand's WorldTour DNA in a lighter package.
