A direct Ksyrium inheritance comes from the rear hub and spoke lacing system. The machined aluminum hub carries a stiff steel quick-release style axle and has stout flanges for the 20 bladed, straight-pull steel spokes. Mavic employs it's IsoPulse lacing system to achieve immediate acceleration and excellent lateral stiffness. IsoPulse lacing offsets hub alignment that is dished to the driveside by lacing the driveside spokes at very high tension in radial formation. The non-drive side gets 2x lacing. This is the opposite of what would be expected and is only possible due to the strength and tension allowed by the technologies of the spokes, rim and hub. To keep the weight low and hub response quick, the fast engaging, serviceable, interchangeable FTS-L steel freehub drive system is used. Sealed QRM steel cartridge bearings keep the whole assembly rolling smoothly, with minimal internal friction.

The alloy front hub has a clean, sleek profile and carries the 20 radially laced bladed straight-pull steel spokes. These are secured at the rim by external brass nipples, which prevent a oxidizing reaction with the spokes so in the rare event you need to true the wheels, it shouldn't require much effort. Sealed QRM steel cartridge bearings keep the whole assembly rolling smoothly, with minimal internal friction riding on a stout steel QR-style axle.

Mavic has opted for a true wheel system by including their Yksion Elite 700c tires. This clincher tire has a single compound rubber that balances wear with grip and durability, and has low rolling resistance. With a 120 tpi casing and flexible protection belt, the ride quality is smooth, with sure cornering feel. Ideal for training or entry-level events, the Yksion Elite can handle all conditions and road surfaces, making it a great match for the box rim profile.

We see the Ksyrium Wheelset as a fantastic upgrade for stock OE wheels or as a dedicated training clincher for those who prefer to limit wear and tear on higher-end wheels. From either perspective, the performance will be positive surprise at the sub $550 standard price point. When matched with the Ksyrium Front Wheel, the pair comes in under 1700 grams and rides with a smooth, responsive assurance that after the initial surprise wears off, you will actually forget about and take for granted until you have to power up a climb, rail a descent ahead of the rain, or haul ass down a gravel road with a farm dog on your wheel. Then you will appreciate the Kysrium Wheelset just a little bit more.
