Endurance riders love the ride quality of our Ksyrium wheels because they’re completely at ease climbing or on the flat and ready for any kind of adventure on the bike. It’s hardly surprising – we’ve designed them to do exactly that.

The box section rim extrusion and low spoke count makes for a smooth and comfortable ride, while the light welded rims give excellent spinning dynamics and climbing abilities. The bladed spokes are radially laced in the front wheel for improved lateral stiffness, while they use our exclusive Isopulse lacing pattern (radial on the drive side, crossed two on the non-drive side) in the rear wheel. Isopulse lacing balances the spoke tension, thanks to a wider drive side bracing angle, resulting in higher lateral stiffness under heavy loads, such as out of the saddle climbing.

Of course, this wheel also sports our famous QRM bearings and axle system, which keeps friction low and speed high without compromising on reliability, so no servicing is needed.

Ksyrium comes with our super balanced Yksion Elite tyres in 25mm. They offer the best blend of low rolling resistance and secure cornering grip, dry or wet, thanks to the supple 120TPI casing and the carefully drawn tread pattern, which keeps road pressure low and quickly drives away water. And at just 215g in a comfortable 25mm section, they perfectly match the wheel’s ability to accelerate and climb at ease.
