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** Installingthis oversized derailleur cage typically requires replacing your chain to accommodate the larger pulleys.
