Ball Kolossos Derailleur Cage Steel For. Etap AXS Road - Bl

By replacing your standard derailleur wheels with a ceramic 12-tooth upper derailleur wheel and a 19-tooth lower derailleur wheel, both mounted on the stiffest cage available, you can achieve less friction, more precise shifting, and better chain retention.

The Kolossos is designed for World Tour victories and ensures maximum drivetrain efficiency, allowing you to ride faster with less energy.

The Kolossos ST model features the same rigid, oversized cage for sharp, accurate shifting and oversized pulleys to reduce friction in the drivetrain. It is equipped with high-quality stainless steel bearings, providing excellent durability and smooth performance at a more accessible price.

Please note that installing this oversized derailleur cage typically requires replacing your chain to accommodate the larger pulleys.

- This model is compatible with SRAM RED & Force ETAP AXS Derailleurs
