Kolossos Derailleur CageKolossos, 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
