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.
