Mavic seeks to exploit the best of the Ksyrium aluminum concept through its many designs, but if there is a true inheritor of the SSC wheel, it is the Ksyrium Pro SL clincher. This version of the redoubtable rear wheel weighs just 795 grams, and employs the full spectrum of Mavic's incredible technological breakthroughs in wheel system development. In this iteration, Mavic has finally pushed the internal rim width to 15mm to edge closer common practice of wider rims. Lighter, more efficient; with superior acceleration and performance. The end result is this standard alloy Ksyrium wheel, exemplifying the best of Mavic's system integration.

The base Ksyrium concept starts with an asymmetrical Maxtal extruded alloy rim and Fore support and drilling. The 26mm profile is machined to reduce weight at non-crucial areas, and the ISM 4D milling process removes as much material between and around the spokes and from the sidewalls as possible. This drops rotational weight for faster acceleration while the softened edges and shaping improve aerodynamics. The lacing is the IsoPulse system, which because of the strength and tension possible from the Zicral spokes, FORE drilled nipple insert system, and the sealed Ksyrium rim allows Mavic to run the 10 driveside wide bladed Zicral spokes in a radial pattern, while the 10 non-drive spokes are laced 2x. The result is one of a very select group of truly laterally stiff rear wheels that still have a level of safety and give under impact. The straight-pull spokes aren't not vertically locked into the hub flanges like a j-bend design, so while the spokes themselves won't give like steel spokes, the system allows the wheel to absorb impacts, protecting the rim and rider. The Isopulse system is also the key to the incredible acceleration and responsiveness you get when you out the hammer down.

Of course, you also get the full complement of standard Mavic technologies such as a SUP welded/machined joint, which keeps the rim inherently strong, with no weak point. The light, stiff machined aluminum hub shell features an oversized alloy axle, QRM+ micro-adjustable sealed cartridge bearing system, and the lightweight aluminum FTS-L freehub body. The system is easily serviceable. The wheel was designed for quick release use with 130mm wide dropouts. Mavic supplies their excellent BR601 QR for sure hold under any circumstances.... Read More
