Feature

●Reduced chain waste: the rear derailleur pulley has a deep tooth design. Deepening the tooth traces and reducing the deep tooth guide wheel of the chain can effectively reduce chain loss, the speed change is crisp and the winding is more stable.
●Excellent workmanship: the rear jockey wheel bearing uses ceramic bearing technology, which significantly reduces friction, CNC cutting, better strength and good rust resistance. The self-lubricating system has good lubrication performance and improves the driving experience.
●Stable rotation: the ceramic balls of the bicycle rear derailleur have self-lubricating and maintenance-free properties, and the rotation is smooth and even. At the same time, the transmission efficiency is higher and driving more labour-saving.
●Ceramic bearing technology: the bearing of the guide roller is a ceramic bearing that greatly reduces friction, a self-lubricating system, good lubrication performance and improves the driving experience.
●Versatile: the front derailleur pulley is better compatible and the chain does not get caught when driving. It is suitable for 8, 9, 10 and 11 speed rear derailleurs. The outer diameter of the installation shaft is compatible with 4mm, 5mm and 6mm. Colorful look makes your bike look cooler.
