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.
