Ekar GT is Campagnolo's mechanical 1x13 gravel groupset, and this robust aluminium crankset is its foundation: simple single-ring gearing, strong steel semi-axles and bearings you can inspect without pulling the cups.

Highlights

  • 1x13 gravel drivetrain: no front derailleur, better chain security
  • Aluminium arms with AISI 630 steel Ultra-Torque semi-axles
  • Pro-Tech Hirth-joint axle joined by a single screw
  • Five 7075 aluminium chainrings, 36T to 44T, 104 BCD
  • Crank lengths 170, 172.5 and 175mm
  • 151mm Q-factor

Pro-Tech durability

Pro-Tech joins the two semi-axles inside the bottom bracket with a single sturdy screw. The oversize stainless steel bearings sit on the crank, so they're easy to inspect and service without removing the cups.

Easy gearing changes

The 7075 aluminium rings bolt to four symmetrical arms on a 104mm BCD and swap without removing the crankset, so changing ratio for different terrain is quick. Claimed weight is 850g (172.5mm, 38T).
