KOGEL PULLEY KOLOSSOS w/INNER CAGE OS SHIM 9200/ROAD
KOGEL PULLEY KOLOSSOS w/INNER CAGE OS SHIM 9200/ROAD
This oversized derailleur cage fits Shimano's DURA-ACE RD-R9250 and ULTEGRA RD-R8150 Di2 rear derailleurs.
Kolossos is the Greek word for a statue, much larger than the original subject. Seems fitting for an oversized derailleur cage.
Imagine the performance of replacing your stock pulleys with a ceramic 12-tooth top pulley and a 19-tooth bottom pulley built on the stiffest cage on the market.
Besides being designed for World Tour victories, Kolossos gives you reduced friction, improved shifting accuracy, and better chain retention.
