A true high performance road rim that builds into a light and strong wheel. The SUP rim has a stronger arc-welded joint which is then milled to form an invisible join, eliminating juddering when braking. The Maxtal alloy is 30% stronger than 6061 without any extra weight, resulting in an extremely high strength to weight ratio. Anodised finish to reduce wear and corrosion. UB Control gives the rims a higher coefficient braking surface and a smooth joint due to the digital milling process after anodisation. Drilled for standard road Presta valve tubes….
