What Kolossos Does for You

Besides reduced friction, this cage is built with shifting accuracy, gravel worthiness and chain retention in mind.

- This model will fit on 12-speed Sram Red and Force eTap AXS derailleurs.

- It also fits on 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.

- Installing this oversized derailleur cage typically requires replacing your chain to accommodate the larger pulleys.
