ROSE Bikes KSYRIUM 30 Disc Centerlock 28“/700C Road Rear Wheel SHIMANO HG| Road

Less friction, less rolling resistance, less effort.
The MAVIC KSYRIUM 30 is your entry into the world of high-performance racing.

With a 30 mm high aluminium rim, the MAVIC system wheel combines aerodynamics and stability. The material thickness has been precisely tuned to achieve a good balance between rigidity, durability and a lower weight.
At the same time, the flat rim profile offers little surface even to strong crosswinds. This means you won’t have any problems with the riding stability of your wheel.

The high-quality MAVIC Infinity hubs are connected to the sturdy aluminium rim via aerodynamically flattened straight-pull spokes. A single spoke length also makes maintenance easier.

The double-sealed industrial bearings with self-adjusting bearing preload (QRM Auto) ensure very efficient power transfer and very smooth running.

The next major advantage of the KSYRIUM 30 is its simple tubeless capability. As a result, the wheel from MAVIC not only contributes to improved puncture protection, your ride is also faster and smoother thanks to the improved comfort, which is due to the reduced rolling resistance. This allows you to reach higher speeds with less effort.

And as if that wasn’t enough, the oversized, non-contact rubber seal of the Instant Drive 360 freewheel system reduces internal friction and thus ensures even greater efficiency.

Top technologies:
• Maxtal: Light and strong – this special aluminium alloy offers a better strength-to-weight ratio than conventional 6106 alloys.
• Infinity hub design: Efficient power transfer thanks to optimised non-contact spoke lacing and tension distribution.
• SUP (Soudé Usiné Process): Particularly stable, arc-welded rim joint where the weld of the rim joint is perfectly flat milled for a seamless, smooth transition to achieve balanced rotation without brake vibrations.
• QRM Auto (Qualité de Roulements Mavic Auto): Smooth-running, double-sealed and maintenance-free industrial bearings with high dimensional accuracy and self-adjusting bearing preload.
• ID 360 Instant Drive: A lightweight and low-friction Dual Ratchet freewheel system for explosive propulsion and reliable power transmission.
• UST tubeless technology: The MAVIC standard for tubeless tyres not only improves traction, comfort and rolling resistance, but also reduces the risk of tyre punctures.
