Bullet derailleur cage kolossos oversized ceramic gold

Are you ready to experience total drivetrain optimization? Kogel introduces Kolossos, the extra large and ceramic derailleur cage. Kolossos is designed to fit and mount seamlessly on 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 transmission between legs and wheels. Kogel's goal was to build a cage so stiff that it holds the chain like a cage, while offering all the benefits of oversized, low-resistance pulleys. Kolossos is 3x stiffer than the 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 wheel 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 the standard Ultegra cage.
