Mavic Ksyrium Pro Disc Road WheelsetThe legacy wheel of the disc brake-compatible Ksyrium Family now gets wider rims and a stepped-up finish for improved ride quality Features:RimsMaterial: MaxtalHeight: 26mm, asymmetricalJoint: SUPDrilling: ForeDisc brake specific profileWeight Reduction: ISM 4DValve Hole Diameter: 6.5mmTyre: ClincherInternal Width: 17mmETRTO Size: 622x17CSpokesMaterial: ZicralShape: Straight pull, bladedNipples: Fore integrated aluminium Count: 24 front and rearLacing: Front crossed 2, rear IsopulseHubsFront and Rear Bodies: AluminiumAxle Material: AluminiumAdjustable sealed cartridge bearingsFreewheel: Instant Drive 360Front: Quick release, 12 and 15mm through axle compatibleRear: Convertible to 12mm through axle (135 and 142)TyreYksion Pro GripLink (front) & PowerLink (rear)Front and Rear Tread: Single CompoundCasing: 127 TPIBreaker: Front Kevlar, Rear polyamideDimension: 25-622 (700x25c)VersionsDisc standard: 6 Bolts or Centre Lock(R)Compatibility Freewheel: Shimano/SRAM, convertible to Campagnolo and XD-R with optional driver bodiesFront Axle: Convertible from 12mm thru axle to quick release or 15mm thru axle with optional adaptersRear Axle: 12mm thru axle, convertible to Quick Release with optional adaptersDelivered WithFront 12mm adaptersRear 12x142mm adapters for Instant Drive 360 Specific disc boltsMultifunction adjustment wrenchUser guideWeight: Pair: 1595g Front: 730g Rear: 865g Tyre 700x25: 210gTechnologies:GripLink: A front tyre must fully liberate the wheel’s ability to hold the ground and control the bike. Therefore, GripLink tyres are optimised for front use, by offering a superior grip and extra puncture protection The safest grip with great steering control: Grippy tread compound and water evacuation tread patternHold the road in any situation: Light and supple high density casingReduced risk of flats: Strong Kevlar anti-puncture breakerPowerLink: A rear tyre, whether a clincher or a tubular, must fully liberate the wheel’s ability to transfer power and generate speed. Therefore, PowerLink tyres are optimised for rear wheel use, by minimising the rolling resistance Superior energy transfer, reduced rolling resistance and safe grip thanks to optimised tread patternImproved drive: Light and supple high density casingHigher durability and reduced risk of flats: Nylon anti-puncture breakerQRM+ (Qualité de Roulements Mavic +): Mavic's most demanding level. Those cartridge bearings are of course double sealed with C3 internal clearance and topped with a micro-adjustability system Tight tolerances for high rolling efficiencyQuick adjustment according to performance goals: Precision "free" adjustment for maximum fluidity, or perfect high precision setting for all-weather ridesIsopulse (Optimum energy transfer): The spokes are laced radially on the drive side and crossed 2 on the non-drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges Higher stiffness under heavy loads for crystal clear energy transmission Better wheel stability for fewer maintenanceFore (Stiffer and stronger): Instead of being drilled, the lower rim bridge is pushed up on the inside and then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intact Rim is 4 times more resistant to fatigue stress20% increase in the rim rigidity to maximise power transferZicral (Light, stiff and strong): A specific aluminium alloy that provides spokes with higher stiffness-to-weight ratio while being stronger Lighter spokes for easier climbingStiffer spokes for better energy transmissionStronger spokes for increased durabilityMaxtal (Light and strong): Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than conventional 6106 alloy 30% more resistant rimsLighter rimsSUP (Stronger and smoother joint): Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish Extremely strong rim joint Eliminates shuddering when braking Superior wheel balanceInstant Drive 350: The Instant Drive 360 freewheel system is super light and fast to engage with only 9°. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile Oversize aluminium axle and hardened alloy freewheel driver body saves 40g40 teeth dual ratchet system provides fast 9° engagementRadial seal provides low friction for higher speed and perfect waterproofnessComprehensive end cap adapters make it compatible with any type of retention system and driver body (QR, 12x142, HG, ED…)ISM 4D (Inter Spoke Milling 4 Dimensions): An exclusive Mavic patented concept, ISM 4D significantly reduces weight and inertia without compromising durability. The smooth profile also helps reducing aerodynamic drag 15% lighter rim, the lowest inertia for instant acceleration, better handling and faster climbingVariable rim thickness optimises constraints management for more reliabilitySmoother rim profile offers better air flow which reduces drag for higher speedBuy Mavic Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
