Kogel Kolossos derailleur cage oversized ceramic Eagle red

Are you ready to experience total drivetrain optimization? Kogel introduces Kolossos, the oversized and ceramic derailleur cage. Kolossos is designed to seamlessly fit and mount onto your current rear derailleur. Oversized derailleur pulleys are all the rage these days. Large derailleur pulleys cause less distortion in the chain and slower rotations in the bearings. Both lead to less friction and more efficient power transfer between legs and wheels. Kogel's goal was to build a cage so stiff it cages the chain, while still providing all the benefits of oversized, low-drag pulleys. Kolossos is 3x stiffer than the main competitor and 2x stiffer compared to the stock cage on your derailleur. Built to provide low friction while maintaining shift accuracy. Built for both racing and off-road use. Designed with long teeth on the lowest pulley for optimal chain tension. Stiffest derailleur cage on the market for the most accurate shifting with an oversized system. Three times stiffer than the competitor, two times stiffer than standard Ultegra cage.
