The 1x chainset is a crucial element in Campagnolo's gravel-specific Ekar drivetrain design. Lightweight, secure and simple up front, with no wasted overlapping gears or unnecessary moving parts to collect trail dirt - one chainring and no front mech is the way to go, whatever your off-road ambitions! But behind that apparent simplicity is a design to die for. Like the whole EkarTM system, the cranks combine strength and lightweight materials. The 2-piece crankset features a strong, durable 630-grade steel alloy axle mated to a polyamide-carbon spider and beautiful UD Carbon arms. New ProTechTM technology joins the two semi-axles inside the BB while oversized stainless steel bearings sit outside the shell, for smoothness, strength and easy access. Specification Lightweight, efficient, secure 1x Ekar system - perfect for gravel riding and racing 2-piece cranks: ultra-torque 630 steel axle & UD carbon arms - strong and lightweight 4 ring options - Adventure (38T), Pure Gravel (40T), Fast Gravel (42T), Gravel Race (44T).
