Campagnoloo Ekar GT Rear Derailleur The Unrivaled Campagnolo Experience12-speed was all the rage back in the day, but now 13-speed is where it's at. The Campagnolo Ekar GT Rear Derailleur is part of a dedicated 1x system and 13-speeds make it effective. The 9-tooth sprocket allows for the birth of a complete range of gear ratios with short evenly spaced shifts and well-maintained cadence levels. The design of the rear derailleur with medium-length housing is compatible with the different sizes of the sprockets on all four of the cassette combination options, from 9-36 to 10-48, perfect for any gravel needs. The parallelogram's 2D trajectory is designed specifically for the Ekar GT 1x system so that shifting entails precise mechanical movements for the best use of the 13 sprockets. Its larger pulley wheels guarantee optimum working and high chain retention for security and peace of mind, whatever terrain you tackle. The clutch, permanently engaged for enhanced chain retention reliability and minimal operational noise, can be locked forward for easy wheel removal. Carbon fiber-reinforced polyamide and anodized 7075 and 6082 alloys are skillfully combined in the Ekar GT rear derailleur's body and cage, for the best blend of strength, durability, and lightweight, ensuring long-term reliability.
