Shimano Oversized Derailleur Cage - DURA-ACE R9200 & ULTEGRA R8100 - Black

Backordered until late May

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.
