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.

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.
