Mavic Open Pro UST Rim - 2020

The UST version of the Open Pro rim combines the high end technologies of Mavic's Wheel-Tire Systems with the benefits of the Road UST technology: reduced rolling resistance, improved ride quality and puncture resistance.

Technologies of the Mavic Open Pro UST rim:

Maxtal - Exclusive to Mavic. An aluminum alloy that is 30% more resistant than a 6106 alloy for lighter and spicier rims.

ISM 4D (Inter Spoke Milling 4 Dimensions) - An exclusive Mavic patented concept, ISM 4D not only significantly reduces weight and reduces inertia without compromising durability, but also improves aerodynamics due to its new rim shape. Further advantages: up to 50 grams lighter for faster climbing, the lowest inertia for instant acceleration and a smooth aerodynamic rim shape to reduce drag.

SUP (Soudé Usiné Process) - A welded and milled rim joint which is extremely strong, eliminates shuddering when braking and offers superior wheel balance.

UB Control (Usiné Brut Control) - The braking surfaces are milled to improve braking friction and eliminate shuddering.
