Kogel KOLOSSOS derailleur bracket with pulleys, SRAM EAGLE, gold
Kogel KOLOSSOS derailleur arm with pulleys
Oversized derailleur pulleys are all the rage these days. The large pulleys of the derailleur cause less deflection of the chain and slower rotation of the bearings. Both lead to less friction and more efficient power transmission. The guide is designed for SRAM XX1 Eagle, X01 Eagle and GX Eagle MTB derailleurs, including the AXS version.
Kolossos is 3x stiffer than competing products and 2x stiffer compared to the original pulley cage on your derailleur
