Mavic Allroad SL Road Disc Wheelset - Black - Shimano HG}, Black
  • £589.99

Mavic Allroad SL Road Disc WheelsetPrepared for every gravel bike adventure, this wheelset features a lightweight aluminium rim construction that offers smooth and responsive handling when the smooth tarmac comes to an end. Mavic has also equipped this model with its renowned ISM4D technology, which removes material from the rim where it's not needed but keeps it around the spokes, where tension is applied. This means that you'll enjoy its fantastic strength, without any unnecessary weight holding you back. Double-butted spokes further reduce its weight and make each wheel feel more responsive. The spokes have an aero elliptical shape that can save 5 watts of energy while maintaining your speed. Available in either a 650b Road+ option or a 700c version, this wheelset is engineered to deliver a faster and smoother rider on rough roads, gravel and dirt. Allroad SL Road+ 650bThis version features super-wide rims (25mm internal) that 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.Allroad SL 700cThis version features wide rims (22mm internal) that are compatible with tubeless tyres ranging from 28mm to 64mm for a smooth, efficient ride quality.Lightweight, Tubeless Ready Gravel WheelsetMavic's UST tubeless system has been improved with a revised 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 (another 30g saved).Infinity Hub and Instant Drive 360 FreewheelMavic's Infinity hub platform optimises spoke lacing with highly controlled tension for maximum power transfer, and the Instant Drive 360 freewheel, coupled with the automatic bearing preload adjustment (QRM Auto), provides fast engagement, stiffness and added durability. The wheels use centre-lock brake rotors and are available in Shimano or SRAM XD-Road driver bodies options to choose from. This model can able be converted to Campagnolo with an optional driver body (sold separately). 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.Features: Rim Material: Aluminium, Hookless profile Hub Material: Front and Rear Bodies: Aluminium; Axle: Aluminium Spoke Material: Steel Use: Road, Gravel Rim Height: 22mm Internal Rim Width: 650b: 25mm; 700c: 22mm ETRTO: 650b: 584x25TSS Road; 700c: 622x22TSS ROAD Tubeless Ready: Yes, UST tubeless technology Brake Type: Disc brake specific profile Tyre Compatibility: UST Tubeless and tube type Rim Technologies: SUP welding technology and Fore tapeless tubeless technology Front Axle: 12mm thru-axle, easily convertible to quick release with optional adaptors (available separately).

Shimano Dura-Ace R9270 C36 Carbon CL Disc Wheel Wheel Sets
  • £549.99
  • RRP £859.99
  • Saving you £36

With stunning acceleration, the new Dura-Ace R9270 C36 wheelset will change the way you experience climbs, corners, even stoplights. This is because it isn't just how much a wheel weighs but where the weight is on the wheel that matters. The all-new C36 design shaves mass at every opportunity but especially at the rim. The result is a lively wheelset that can transform your ride. Lighter, Wider and Faster Carbon Road Race Wheel With both a lighter, wider all-carbon rim and a lighter hub, the new Dura-Ace C36 won't shy away from a day of climbing. The new rim is 36 mm deep and still delivers good aerodynamic efficiency despite its gossamer weight. Meanwhile, the hub features an alloy freehub body and a new engagement mechanism for increased rigidity. Centre-Lock Disc Rotor Mount The Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency. D2 Aerodynamic Rim Profile Aerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tire bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road. Rear Wheel OPTBAL Spoke System The OPTBAL rear wheel spoke system features 21 spokes—14 on the drive side and 7 on the non-drive side. Cassette spacing in today’s wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally, high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel. Shimano E-Thru Axle System The tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.
