The Campagnolo Ekar rear derailleur is designed for dedicated gravel and all-road cyclists who demand precision, durability, and a wide gear range in a 1x13 drivetrain setup. By utilizing a 2D parallelogram trajectory and high-quality construction materials, this derailleur delivers consistent shifting performance across challenging, uneven terrain. While it offers industry-leading integration for Ekar groupsets, users should note that it is specifically optimized for Ekar-only components and requires precise setup to maintain its specialized 13-speed performance.

No, the Ekar 13-speed derailleur requires Ekar-specific 13-speed shifting components to operate correctly.
The Ekar derailleur is designed specifically for use with the three official Campagnolo Ekar cassette options.
The unit weighs approximately 275g, balancing durability with lightweight performance.
The Clutch Lock holds the derailleur in a fixed position, making it easier to remove and install the rear wheel without fighting the chain tension.
Depending on the conditions, you should clean and lubricate the pulleys after every few rides, or immediately after riding in wet, muddy, or dusty conditions.
Check that your derailleur hanger is perfectly aligned and verify that the cable tension is calibrated precisely for the 13-speed spacing.
Verify that the clutch is engaged properly and inspect the pulley wheels for dirt or damage that might be disrupting smooth chain travel.
Ensure the lock mechanism is free of dried mud or grit. If the issue persists, inspect the lock spring for debris or signs of wear.
To ensure optimal performance, the Ekar derailleur must be paired with an Ekar-specific 13-speed cassette and the corresponding Ekar shifter. Installation requires standard derailleur alignment tools; ensure the hanger is perfectly straight before indexing the gears. When performing routine maintenance, clean the pulley wheels regularly to prevent debris buildup from affecting shifting precision. Periodically check the stainless steel bolts for proper torque as recommended in the technical manual. The use of a high-quality dry or wax-based lubricant is recommended to protect the internal components and pulleys from grit and moisture common in gravel riding.
