UST Tubeless-Ready Road Bike Rim

Whether you’re riding with your local club or taking part in an event, this road rim’s UST tubeless-ready technology improves traction, control and comfort while reducing inertia and flats. This means that riders can easily run tubeless tyres and enjoy benefits such as lower rolling resistance, greater stability and fewer chances of punctures wherever their ride takes them. Coming complete with a 19mm internal rim width, this version is compatible with tyres up to 47mm as well as tyres as narrow as 25mm.

Technologies:

• Maxtal: Light and strong. Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than conventional 6106 alloy.
• UST Tubeless Ready: The UST concept improves traction, control and comfort while reducing inertia and flats. The tubeless-ready construction results in a lighter tyre for improved performance. The rim bed shape makes it easy to mount any tyres, tubeless and tube-type.
• SUP (Soudé Usiné Process): Stronger and smoother joint. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
• ISM 4D Light Rim Technology: Inter Spoke Milling 4 Dimensions. An exclusive Mavic patented concept, ISM 4D significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance; the right mix to make the most of any ride. The smooth profile also helps to reduce aerodynamic drag.
