Mavic Ksyrium SL 25 Disc Wheelset

Ksyrium has always represented the best in aluminium wheel technology. In the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the brand new Ksyrium SL Disc has no reason to blush. Looking for a wheelset for weekend racing and training distance? Wherever the road takes you, it's the safest choice.

This new wheel is extremely light (120 g less than the old Ksyrium Elite UST Disc) and still just as durable thanks to our patented ISM 4D process. This machining process makes it possible to remove all the excess material between each spoke hole, while maintaining sufficient wall thickness where the tension of the spokes and the stresses are the greatest. These rims are made in France, in our aluminium rim factory.

Butted spokes help further reduce weight and make for an even more responsive wheel. Their patented elliptical shape also saves energy to increase efficiency.

Fore technology reinforces rigidity. The upper bridge of the rim is not drilled; it therefore remains resistant and rigid, and does not require the installation of a rim tape (another 30 g less per wheel). With the new profile of the upper bridge of the rim, mounting and demounting a tire has never been so easy; our UST Tubeless technology reduces rolling resistance and increases grip while limiting the risk of punctures. Our new Infinity hub platform optimizes stiffness and power transfer, thanks to carefully tuned spoke tension. The Instant Drive 360 freewheel body, combined with the automatic adjustment of the QRM Auto bearings, guarantees quick engagement, good rigidity and increased durability. Designed specifically for disc brakes, these wheels are compatible with a 12 x 100 front axle and a 12 x 142 rear axle. For Center Lock brake rotors only.
