Kogel derailleur cage oversized ceramic

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 that is so stiff that it holds the chain like a cage, while providing 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.
