For the latest version of the Helium SLX, the Ridley R&D department wanted to improve rigidity and responsiveness. In the past, this unique stiffness and responsiveness in conjunction with its weight was the secret recipe behind the success of the Helium family. When Cadel Evans asked Ridley engineers for a climbing bike, his main comment was: "Weight should never be at the expense of stiffness."
Our Ridley engineers listened carefully to Evans and found the ideal balance. The riders fell in love with the frame. Every new development in the Helium range was implemented according to the same reasoning: "Stiffness and responsiveness together with weight are the number one consideration. None of the three must be a higher priority than the others.”
It was quickly decided that the down and top tube shape of the Helium SLX would not be modified. A (flattened) circular shape still guarantees the best stiffness-to-weight ratio. If you change the circle, you’ll change the weight or stiffness.
