The Campagnolo Ekar ProTech bottom bracket has been specially designed to cope with the tough conditions of off-road and gravel riding. It features ProTech technology, namely a patented external seal that protects the ball bearings from the penetration of water, mud and sand, and a central watertight ring made of glass fibre-reinforced polyamide to prevent contamination from the inside. The new cups fit the oversized stainless steel outer bearings mounted on the two Ultra-Torque half axles securely attached to the cranks. Ekar's bottom bracket options offer excellent compatibility with the frames on the market thanks to a full range of threaded and PressFit cups.
