Mavic Ksyrium SL Heritage C-Lock 700c Wheelset

Ksyrium has always represented the best of aluminium wheel technology. Following in the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the Ksyrium SL takes it to the next level. It's the perfect all rounder for those seeking a wheel that delivers reliable everyday performance on the road.Superlight and durable for everyday performanceISM4D rim weighs only 400gPatented lightweight aero spokes and 22mm deep/19mm wide rims keep inertia low and control highSolid upper rim bridge eliminates the need for rim tape, saving 60gLaterally stiff, vertically compliant for a more dynamic rideFore technology keeps the rim upper bridge solid to make the rim stifferInfinity hub platform: stiff axle, durable bearings and new hub design guarantees wheel stabilityID360 freewheel technology for improved power transferImproved UST Road delivering speed, comfort and controlNo tubes means less friction, improved efficiency and grip with reduced risk of puncturesRim bed shape makes it easier to mount and change tyresFore Carbon drilling technology means no rim tape is requiredWeightPair: 1575gRear: 852gFront: 723gUnderstanding the different Mavic freehub body acronyms:HG or M11 – Shimano HG Road 11/12x (other speeds with spacer)MS - Shimano MicrosplineXD - SRAM XDXD-R - SRAM XD-RED11 - Campagnolo 9/12xN3W - Campagnolo 13xThis new wheel is superlight (120g lighter than the former Ksyrium Elite UST Disc) and durable as ever thanks to our patented ISM4D technology. This manufacturing process removes all excess material between each spoke hole while keeping the rim wall thick enough where spoke tension and stress is the highest.The double-butted spokes contribute to the weight reduction while making the wheel more responsive. These spokes also have a patented elliptical shape that can save 5 watts for added efficiency.Stiffness is optimised using Fore technology. The upper bridge is not drilled, so it remains strong and rigid and doesn’t require the use of a rim tape (another 30g saved per rim). The rim bed's shape makes it easier than ever to mount and remove tyres, and the UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. The Infinity hub platform optimises stiffness and power transfer with highly controlled spoke tension, while the Instant Drive 360 freewheel coupled with our automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability.Available for Shimano, Campagnolo or SRAM XD-Road.Maxtal aluminium alloyLight and strong. Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than the conventional 6106 alloy.ISM 4D Light rim technologyInter Spoke milling 4 dimensions is an exclusive Mavic patented concept. Significantly reducing weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance. The right ratio to make the most of every ride. The smooth profile also helps reduce aerodynamic drag.Fore tapeless tubeless technologyStiffer and stronger. Instead of being drilled, the lower rim bridge is pushed up on the inside, then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intactInstant Drive 360 technologySuper light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.UST tubeless technologyTraction and control. The UST concept improves traction, control and comfort whilst reducing inertia and flatsSUP Welding technologySoude Usine Process, stronger and smoother joint. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.Infinity Hub DesignAn ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear.QRM Auto bearing preload technologyQualite de Roulements Mavic Auto. Cartridge bearings are double sealed with e3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run.Technical Specifications:Profile depth: 22mmInner width: 19mmFront axle: 12x100mmRear axle: 12x142mmDiscipline: RoadSpokes: Steel, Straight, AeroRim Diameter: 700cNipples: Brass, BlackRim material: Maxtal Aluminium alloyTyre compatibility: UST Tubeless ReadyMaximum weight: 120kg including bikeBearings: AluminiumETRTO Size: 622x19TCWeight: 1575gWhat's in the box?WheelsetUser guideUST valve not mounted on wheel2 Multifunction adjustment wrench with the rear wheelIntended UseMinimum tyre size: width 23mm - pressure max. 6.75Bar/97PSIMaximum tyre size: width 62mm - pressure max. 3.8Bar/55PSIASTM category 2 : road and offroad with jumps less than 15cm
