The Campagnolo Ekar Rear Derailleur – 13 Speed

Although the Ekar derailleur draws inspiration from our Super Record and other advanced systems, it stands apart as a purpose-built solution for gravel riding. Developed exclusively for the demands of a dedicated 1x setup and the innovative 13-speed configuration, Ekar’s design centers around a pioneering 9-tooth sprocket. This enables a broad gear range with closely spaced ratios, ensuring smooth cadence and efficient shifting across all terrains.

Every element—from technology choices to material selection—has been tailored to not just meet, but surpass the unique challenges of all-road and gravel cycling. The result is lightning-fast, accurate, and dependable shifting, paired with outstanding chain retention, low weight, and remarkable durability—qualities essential for serious off-road adventures.

A single, mid-length cage rear derailleur accommodates all three cassette options (9-36, 9-42, and 10-44), adapting seamlessly to any gravel setup you prefer. The parallelogram mechanism is engineered for precise 2D movement, perfectly aligned with the Ekar 1x system to deliver crisp, reliable gear changes across all 13 sprockets. Differentiated tooth counts on the pulley wheels ensure smooth chain flow and secure retention, giving you confidence no matter how rough the ride.

The derailleur’s clutch system is always engaged for superior chain stability and quiet operation, but can be locked forward to simplify wheel changes. With over 70 individually designed and engineered components, the Ekar derailleur combines carbon fiber-reinforced polyamide with anodized 7075 and 6082 alloys, striking an ideal balance between strength, lightness, and resilience. Stainless steel bolts add further robustness, ensuring the derailleur endures the harshest conditions, from dust and grit to the inevitable impacts of hardcore gravel riding.
