Description
Kolossos, derived from the Greek word for a statue much larger than its original subject, aptly describes this oversized derailleur cage. By replacing your stock 12-tooth pulleys with a 14-tooth top pulley and a 19-tooth bottom pulley, both mounted on the stiffest cage available, you can achieve reduced friction, improved shifting accuracy, and enhanced chain retention. This design ensures maximum drivetrain efficiency, allowing you to ride faster with less energy.
The Kolossos ST model offers the same oversized design with high-quality stainless steel bearings, providing excellent durability, smooth performance, and long-lasting reliability at a more accessible price point.
This model fits all 12-speed SRAM Red and Force eTap AXS derailleurs intended for 2x setups, including the latest SRAM Red groupset (2024). Please note that installing this oversized derailleur cage typically requires replacing your chain to accommodate the larger pulleys.
