Mavic's Exalith 2 braking system offers exceptional all-conditions stopping power and feel, and when found on a Ksyrium wheel, the all-rounder gets even better. The Ksyrium Pro Front Exalith SL Front clincher wheel is built with a full complement of Mavic technology, with its machined Maxtal rim, QRM+ bearings, Zicral spokes and much more, and has the lighter weight 15mm internal rim width that Ksyrium riders know and love at a 605 grams. The changes over time have been refinements to the well proven concept that is light, fast, and durable, but adding Exalith II is a substantial upgrade. Both serious enthusiasts and racing cyclists alike have long enjoyed the serious, highly predictable performance of the Ksyrium, especially when cornering and sprinting where trust is everything, and with Exalith 2, braking in the rain exceeds the overall performance.

The Ksyrium concept starts with Maxtal extruded alloy rims and Fore support and drilling. The rim is machined to reduce weight at non-crucial areas, and the ISM 4D milling process removes material between the spokes and just onto the sidewalls. This drops rotational weight for faster acceleration while the shaping improves aerodynamics. The double-butted Zicral spokes thread directly into the rim via a nipple carried by the spoke. The spoke holes are reinforced through lower rim bridge, leaving a sealed outer rim wall. The Zicral spokes are a flat, bladed design cable of very high tension. The rims are front and rear specific, with a 24mm profile in front. 18 straight-pull spokes in the front, laced radially, provide incredible lateral stiffness and perfect tracking at any speed.

Exalith 2 is a chemical treatment of the rim penetrates the alloy to strengthen and add an even friction to the braking surface that is exceptionally durable and increases braking by around 20% in wet conditions over standard machined rims and normal pads. Mavic provides black, Exalith-specific brake pads are durable, quiet, and formulated to work perfectly with the rim treatment.

Standard Mavic technologies such as a SUP welded/machined joint and the QRM+ adjustable sealed cartridge bearing system. The front hub itself has a carbon shell bonded to large alloy flanges that carry an oversized alloy axle. The wheel was designed for quick release use with 100mm wide forks. Mavic supplies their excellent BR601 QR for sure hold under any circumstances. At 605 grams for this front wheel, the Ksyrium Pro was built for everyday performance riding.... Read More
