Mavic Ksyrium SL Rim Brake QR XDR Rear

Lightweight and very durable laterally stiff but vertically compliant. The Ksyrium SL raises the bar setting a new standard for aluminum road wheels.

Ksyrium has always represented the best of aluminum 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.

**Features**

**Superlight and durable for everyday performance**

* ISM4D rim weighs only 400g

**ADDITIONAL INFORMATION**

This wheel is lightweight and durable as ever thanks to Mavic's 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 further reduce weight 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 cassettes and can convert to Campagnolo or SRAM XD-Road with optional driver bodies.

**Technologies**

**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.

**Isopulse lacing design**

Optimum energy transfer. The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise the drive side dish thus providing an improved spoke tension balance between left and right flanges.

**UST tubeless technology**

Traction and control. 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**

An 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 technology**

Qualite 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.

When will my order arrive? (excluding Bikes)

Just above the 'Add to basket' button you will see the item availability. We have 3 different availability stock flags on our website which will determine how long an order will take to arrive.

In Stock in Kircaldy Shop
This means that we physically have the item in the shop. If you choose one of our Priority Delivery options then you can expect your order within 1 to 3 working days. If you choose a Non Priority Delivery service you can expect your order within 3 to 5 working days.

In Stock at Supplier
Our stock system is linked in with our suppliers stock system which allows us to offer a wider product range, but does increase the delivery times a little. If you choose one of our Priority Delivery options you can expect the order within 3 to 5 working days. If you choose Non Priority Delivery you can expect the order within 5 to 10 working days, although this is completely determined by the speed of the item coming from our supplier.

Out of Stock
This means that both ourselves and our suppliers are out of stock of the item. Although the website won't allow you to order something with this stock flag you are more than welcome to contact us with the Product ID. We may be able to back order it for you, or at least see if we can provide an estimated restocking date.

If you need an order quicker than this please email us with the product ID to find out if this is possible to avoid disappointment.

What about bikes?

We aim to dispatch all bikes within 5 working days, but during busy periods we may have a few builds in the queue and could take a bit longer. If this is a concern or you need the bike before a certain date then please email us to make sure we can achieve this and avoid any disappointment. We will email you the day of dispatch and you can expect the bike the following day. If you provide a mobile number on your order the courier will also send you a text message 1 hour before delivery so you know exactly what time to expect it.

Who do you use to send orders?

We use Royal Mail for most of your orders unless they are bulky or valuable, in which case we will send the order using DPD. You can also specify DPD at checkout if you prefer to have your item delivered with an hours notice in the form of email or text from the courier.
