Ksyrium Pro Exalith SL Limited
A wheel that combines a racer's responsiveness and lightweight performance with a smoother deeper rim
The Ksyrium Pro Exalith SL is a lighter and stiffer version of Ksyrium Pro Exalith. It pushes weight-saving one step further making it a high performance choice for any kind of ride. Like the Pro Exalith this wheel features the same Fore technology and Zicral spokes that bring higher stiffness and strength at a very low weight.
It also features the Exclusive Exalith technology a chemical treatment of the aluminum alloy that slows down wear notably at the brake track. It also shortens braking distance by 20% in dry and wet conditions and provides a stunning all black finish including on the brake track that will keep its colour for thousands of kilometers.
ISM4D and Tracomp technology
The rim uses ISM4D technology to keep weight and inertia very low saving four watts in aerodynamics.
In addition it uses our patented and unique Tracomp technology on the rear wheel. Tracomp stands for Traction/Compression. It was first introduced on the R-Sys wheel where we�ve been able to lower the wheel weight again by 10% while increasing lateral stiffness by 30%.
So why does Tracomp make such a difference? Well a traditional wheel works with spokes that are only tensioned. The spoke tension provides the frontal and lateral stiffness and keeps the wheel components together. But under lateral loads half of the spokes will see their tension increase and the other half will see it lowering. When the load is very
