Allroad Sl Road+ Disc 650B

This "Road+" Allroad wheel is made with wider rims and a 650B diameter to help you tackle the roughest roads, cobbles, gravel or dirt with speed, control and a dynamic ride quality **Traction, rolling efficiency and confidence on all types of terrain** * Wider 650B rims let you run larger, high volume tyres and still maintain the responsive handling of a normal road bike * 5cm of plush "tyre travel" improves traction and comfort, prevents pinch flats, and lets you dial in the perfect tyre pressure for the terrain * UST Tubeless compatibility for lower rolling resistance **Superlight and durable** * ISM4D rim is only 440g * Patented lightweight aero spokes * Automatic bearing preload (QRM Auto) requires no adjustment and guarantees long term durability * Fore drilling doesn't require the use of rim tape - 30g saved per wheel **Laterally stiff and vertically compliant for a dynamic ride quality** * Fore technology keeps the rims upper bridge solid to make the rim stiffer * 17mm axle and new hub design * ID360 freewheel technology is 12mm compatible, convertible to quick release (plus 15mm axle option through axle replacement) **Weight Pair: 1555g** **Understanding the different Mavic freehub body acronyms:** * HG or M11 – Shimano HG Road 11/12x (other speeds with spacer) * MS - Shimano Microspline * XD - SRAM XD * XD-R - SRAM XD-R * ED11 - Campagnolo 9/12x * N3W - Campagnolo 13x ___ **ADDITIONAL INFORMATION** The lightweight aluminium rims feature ISM4D technology, which strategically removes material from the rim where it's not needed but keeps it around the spokes, where tension is applied. Double butted spokes further reduce weight and make the wheel feel more responsive. The spokes have an aero elliptical shape that can save 5 watts of energy while maintaining your speed. Super wide rims (25mm internal) are compatible with tubeless tyres up to 64mm to absorb road shocks and vibrations. You get 5cm of "tyre travel" to cushion your ride, and the smaller diameter rims allow you to retain the agile handling you want with a drop bar bike. Our UST system has been improved with a new rim bed shape that makes it easier than ever to install and change tyres. Fore technology attaches the spokes to the rim without the need to drill the upper rim bed, so no tape is required, no hassles, no added weight. Our new Infinity hub platform optimizes spoke lacing with highly controlled tension for maximum power transfer, and the Instant Drive 360 freewheel, coupled with our automatic bearing preload adjustment (QRM Auto), provides fast engagement, stiffness and added durability. The wheels use centre lock brake rotors and are available with Shimano, Campagnolo or SRAM XD-Road driver bodies. The front hub is a 12mm thru-axle that can convert to 15mm or quick release. The rear is a 12x142 and can also convert to quick release. **Maxtal aluminium alloy** Light 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 technology** Inter 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 technology** Stiffer 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 intact **Instant Drive 360 technology** Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile. **UST tubeless technology** Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats. **SUP Welding technology** Soude 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 design** Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution. **QRM Auto bearing preload technology** Qualite de Roulements Mavic Auto. Cartridge bearings 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: 22mm * Inner width: 25mm * Front axle: 12x100mm * Rear axle: 12x142mm * Discipline: Gravel * Spokes: Steel Straight Aero * Rim Diameter: 650B * Nipples: Brass, Black * Rim material: Maxtal alloy * Tyre compatibility: UST Tubeless Ready * Maximum weight: 120kg including bike * Braking system: Centre lock only * Bearings: Aluminium * ETRTO Size: 584x25TSS * Weight: 1555g **What's in the box?** * Wheelset * User guide * UST Valve not mounted on the wheel * 2 multifunction adjustment wrenches **Intended Use** * Minimum tyre size: width 30mm - pressure max. 4.05Bar/59PSI * Maximum tyre size: width 64mm - pressure max. 2.45Bar/36PSI * ASTM category 2 : road and offroad with jumps less than 15cm
