Shimano GRX and Ultegra RX800 Oversized Derailleur Cage - Black

Kolossos is the Greek word for a statue, much larger than the original subject. Seems fitting for an oversized derailleur cage with a 19 tooth bottom wheel.

Besides reduced friction, this cage is built with shifting accuracy and chain retention in mind. Kogel Bearings has always had a strong connection to off-road disciplines. We wouldn't build it if it weren't gravel proof.

Oversized pulley systems are an excellent way of reducing the additional friction caused by clutch derailleurs. Run it on a 1x or 2x setup, it is your prerogative.

This model will fit on GRX and Ultegra RX800 series derailleurs. This includes mechanical and Di2.

 ** Please note this is a discounted presale price. Product will ship on febrero 3.
