Drivetrain

Campagnolo Ekar groupset is no conventional gravel groupset.
Ekar is the lightest complete gravel groupset in the world: reliable and high-performance.

The EKAR chain mates effectively with the wide-narrow teeth design of Ekar's 1x13-speed chainrings and cassette sprockets for a positive, efficient, low-friction drive, and benefits from high security.

The EKAR C13 chain is a vital element of the Ekar mechanical groupset; along with providing an efficient drive, in gravel riding a chain must work perfectly to contribute to the derailleur smooth, quick gear shifts, and always remain secure

EKAR 13 SPEED SPROCKETS
The 1x system works best for gravel, with the 13-speed configuration enabling that to work across a full range of gearing ratios – and what underpins that is the use of a 9-tooth sprocket.

The Ekar rear derailleur is designed using Campagnolo's peerless experience and ingenuity which has been developed and honed over more than 80 years of innovation.

EKAR CRANKSET 1X13 SPEED
The crankset is the heart of the new 1x Ekar system, with its optimised gearing ratios, sensitively spaced across a wide range.

Our Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform.
