RAM eTap AXS users can go big now. 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.
Besides reduced friction, this cage is built with shifting accuracy, gravel worthiness and chain retention in mind.
Compatibility: This model will fit on SRAM Red and Force eTap AXS 12 speed derailleurs with a 2X Set up including the recently released Red AXS 12sp updated derailleur. This product is not compatible with SRAM Rival eTap AXS derailleurs.
** Please note Installing this oversized derailleur cage typically requires replacing your chain to accommodate the larger pulleys. Full installation instructions can be found here
**Kolossos is a component upgrade for Sram eTap AXS derailleurs. Derailleur not included**
