Mavic's Ksyrium S disc wheels make a great first upgrade, able to significantly boost performance thanks to the brand's advanced technology. The shallow Maxtal rims keep weight low thanks to a unique drilling technique and if you set up tubeless, there's no need for rim tape and tyre mounting is quick and easy. The ride is laterally stiff without compromising compliance, so you get a good blend of responsiveness and comfort.Maxtal aluminium alloy rimsMaxtal aluminium is light and strong. A material exclusive to Mavic, it has a higher strength to weight ratio than 6106 alloy.ISM light rim technologyExclusive to Mavic, Inter Spoke Milling technology keeps weight and inertia low, without compromising durability. Machining the lower bridge of the rim between each spoke hole reduces weight while maintaining a rigid structure.Fore tapeless tubeless technologyThe lower rim bridge is pushed up and threaded, rather than drilled. The nipples can then be directly screwed in, leaving the upper bridge intact and eliminating the need for rim tape in a tubeless setup, with a perfect seal created every time.Mavic's Infinity hubs create uniform tension across all the spokes for stability, reliability and a responsive ride. Designed so there is no contact between spokes, the wheel rolls silently, even under high stress or in the event of impact. Every spoke is identical in length, meaning maintenance is simple and the spokes can be changed without dismantling the wheel. A super light and efficient freewheel system that's versatile enough for a range of setups. Engagement is almost instant and a large contactless rubber seal reduces friction for a buttery smooth feel. Mavic's auto bearing preload hub technology keeps the wheels spinning smoothly without play for longer. These double-sealed bearings maximise durability, keeping maintenance to a minimum throughout the wheel's lifetime.
