The Campagnolo EKAR GT crankset features two aluminum cranks that are fitted with Ultra-Torque semi-axles in AISI 630 steel, in line with the clever material combinations of the entire EKAR GT groupset, with a view to producing components that are always light but deliver maximum efficiency and durability. ProTech technology joins the two semi axles inside the bottom bracket, with a single sturdy screw. The oversize stainless steel bearing race is on the crank, fitted onto the semi axle for maximum smoothness and resistance and to make it easy to access for inspection and maintenance without having to dismantle the cups.
