Mavic Ksyrium SR 2012 Road Wheels
The best of Tracomp for multi-performance use. Rely on Tracomp technology for an instant energy transfer and on Zicral spokes for more versatility. This outstanding combination will boost your performance.
Features:
• Responsive: High energy transfer: Tracomp technology on your rear wheel Less inertia for the same stiffness: ISM machining Improved aerodynamics: bladed spokes on your front wheel
• The lightest Ksyrium: 1445 grams: Light and stiff rims: ISM machining Light yet resistant components: reinforced carbon tubular spokes, Zicral spokes, Maxtal rims
• Rely on the proven Mavic quality: Rim resistance: Maxtal, Sup, Fore Drilling High quality adjustable cartridge bearings: QRM+ Reinforced rear carbon spokes
• Weight: 1445 grams, front wheel: 645 grams, rear wheel M10: 815 grams, rear wheel ED11: 800 grams
Technologies:
• SUP: Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish. A welded and milled rim joint is extremely strong, eliminates shuddering when braking, and offers superior wheel balance.
• UB Control: Usiné Brut Control. The braking surfaces are milled to improve braking friction and eliminate shuddering.
• Maxtal: Exclusive to Mavic. An aluminium alloy that is 30% more resistant than a 6106 alloy, for lighter and stronger rims.
• Fore: Only one of the 2 rim wall is "drilled" : - the rim is 4 times more resistant to fatigue stress - 20% increase in the rim rigidity to transfer all of your energy to the ground
• QRM+: Qualité de Roulements Mavic +. Our most demanding level. Those cartridge bearings are of course double sealed with C3 internal clearance, and topped with a micro-adjustability system, allowing you to quickly adjust your wheels according to performance goals: precision "free" adjustment for maximum fluidity, or perfect high precision setting for all-weather rides.
• Zicral: A highly resistant and lightweight aluminium alloy for spokes.
• FTS-L: Force Transfer System Light. Reinforcement of key transmission components: the contact area between the pawl and the hub body is reinforced by 2 stainless steel inserts, which allows the use of a 100% aluminium hub body: - the entire hub is extremely lightweight and strong - greater efficiency due to better transmission of efforts on the entire wheel
• ISM: Inter Spoke Milling Lighter rim and equal rigidity is the magic equation to reduce inertia and to free extra power for climbing. A Mavic patented exclusive concept (US 6 402 256).
• Tracomp: Traction Compression. Tracomp carbon fiber spokes works in traction and compression: - under normal loads, wheel deflection is limited by the very high traction resistance of carbon fibers. - under greater loads, where a normal wheel would flex more because of one of its spoke loosening, Tracomp spokes enter into compression and keep supporting the rim, preventing any further wheel deflection.
