The reference rim for high performance wheel building. Open Pro is the latest version of Mavic "Open" rims, and as such is the most advanced evolution. Optimized up to the limit of material potential, Open Pro is probably the best road rim available.
Mavic Open Pro Road Racing Rim Technologies:
Maxtal: Exclusive to Mavic. An aluminum alloy that is 30% more resistant than a 6106 alloy, for lighter and stronger rims.
SUP: Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish. A welded and milled rim joint 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.
CD: Couche Dure. This process creates a micro surface hardness of the rim. It slows down braking wear and improves its durability.
