Kogel Kolossos Oversized Ceramic Eagle Derailleur Cage Black

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 to your current rear derailleur. Oversized derailleur pulleys are all the rage these days. Large derailleur pulleys cause less deformation 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 would hold the chain like a cage, while providing all the benefits of oversized, low-drag pulleys. Kolossos is 3x stiffer than its main competitor and 2x stiffer compared to the original cage on your derailleur. Built to provide low friction while maintaining shifting 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 precise shifting with an oversized system. Three times stiffer than the competitor, two times stiffer than standard Ultegra cage.
