Campagnolo Ekar 13 Ultra Torque Pro Tech Carbon Crankset Black 172.5 mm / 40t

The crankset is the heart of the new 1x Ekar system, with its optimised gearing ratios, sensitively spaced across a wide range.- Of course, the single chainring is simple to use - no front mech, significantly reduced weight, fewer moving parts to collect dirt or clog, and providing high chain security, with no wasteful gearing overlap - perfect for gravel riding and racing.- The unidirectional carbon fiber cranks feature a strong, durable 630-grade steel alloy crank axle - following the maxim of smartly mating strength and light weight that is employed across the Ekar groupset.- New ProTech technology joins the two semi-axles inside the bottom bracket, with a single, oversized bolt.- Oversized stainless steel bearing sit on the crank, fixed on the semi-axles, for maximum smoothness and strength - and easily accessible for inspection and maintenance without the requirement to extract the cups.- There are four ring size options: Adventure has 38 teeth, Pure Gravel is 40T, Fast Gravel is
