KOGEL Kolosos pulley cage for R9100 R9150 R8000 R8050 (SS/GS).

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 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 12 teeth
• Compatibility: with Shiman-o Dura-Ace 9100 and Ultegra R8000 rear derailleurs, includes both mechanical and Di2 models with short (SS) or medium (GS) cages.

KOGEL BEARINGS Oversized Derailleur Cage System Kolossos | SRAM Red / Force eTap AXS 12-speed

In Greek mythology, the word colossus stands for a statue that is many times larger than the original. If you take a look at the oversized Kogel gearshift cage, the name seems very appropriate.
In addition to the reduced friction, the focus during the development was on perfect shifting precision and rigidity of the system. The cage fits SRAM Red and Force eTap AXS 12-speed rear derailleurs.

IMPORTANT:
When traveling, please remember to dismantle the entire rear derailleur with an Allen key, as very few bicycle transport bags offer enough space for such large rear derailleur cages.

NOTE: The illustrated rear derailleurs are only intended to illustrate the product and are not included in the scope of delivery.
