Exalith is a special chemical treatment that penetrates deep within the aluminum rim material for multiple benefits. First, the rim is reinforced, notably at the brake track, so there’s very low wear over time. Braking power is greatly improved, reducing stopping distances by up to 20% compared to traditional aluminum rims, in both dry and wet conditions. Specific Exalith brake pads ensure quiet braking and limited wear. The rim has a stunning all-black finish that lasts for thousands of kilometers.
We use Fore drilling to keep the rim light and strong, plus Zicral spokes that are stiffer and lighter than traditional steel spokes. Isopulse lacing improves stability and stiffness under high loads, and a new wider rim (17mm internal width) features ISM 4D technology (Inter Spoke Milling) to further reduce weight to just 405g. Excess material is removed from the lower bridge and sidewalls, so the rim is super light but still strong.
Matching Yksion Pro tires, specifically designed for front and rear use, offer an ideal balance of efficiency, grip and light weight. Made with a supple 127 TPI casing, they weigh only 205g in 25mm. The Ksyrium Pro Exalith system is available with 23mm or 25mm tires.
