KOGEL Kolossos Oversized Derailleur Cage & Pulley Set For Sram ETAP AXS 12S Black Sram Red and Force eTap AXS users can now go big! Like Kolossal big! Kolossos is the Greek word for a statue, much larger than the original subject. Sounds appropriate for replacing your 12 tooth pulleys with a 19 tooth bottom and a 14 tooth top pulley, built on the stiffest cage on the market. This model also fits the A2 version of the Red eTap 11-speed derailleur, released in September 2020. If your derailleur is older, this Kolossos does not fit, but the A2 derailleur is compatible with your system. You need a new derailleur in order to fit Kolossos. **Kolossos is a component upgrade for Sram eTap AXS derailleurs. Derailleur not included** Please note** Installing this oversized derailleur cage typically requires replacing your chain to accommodate the larger pulleys.
