Kolosos pulley cage for Sram Etap AXS.
Kogel cages with oversized pulley wheels have proven to be a real advantage on road bikes, and with their exceptional stiffness and pyramid design they improve shifting efficiency and precision.
The Kogel Kolossos is Handmade in El Paso, Texas, USA, with a 7075 aluminum cage and sheaves to improve the resistance of the set, compared to the usual plastic of these elements, and its Kogel ABEC 5 hybrid bearings. with silicon nitride ceramic balls they reduce friction, saving up to 2.5 normalized watts.
Features:
- Large derailleur sheaves cause less chain sag and slower bearing rotations.
- Less friction and more efficient power transfer between the legs and the wheels.
- Kolossos is 3 times stiffer than the main competitor product and 2 times stiffer compared to the original sheave cage on your derailleur.
- Built to offer low friction while maintaining shifting precision.
- Designed with a long tooth profile on the lower pulley for better chain retention.
- Lower pulley with 19 teeth and upper pulley with 14 teeth
- Compatibility: with Sram Red and Force Etap AXS 12-speed derailleurs.
