This product is composed of a carbon cage and two 7075 aluminum pulleys (14 & 17 teeth) with full ceramic sealed bearings.
Our Nova Carbon Ceramic rear derailleur cage improves the smoothness of your transmission, allowing a gain of power to satisfy the most demanding and adding a touch of color to your bike.
Made in very high-end materials: an ultra light carbon fiber cage with two oversized aluminum rollers, which coupled with fully ceramic bearings reduce the chain friction.
This version has a thicker carbon cage than our Shimano road versions in order to be more solid in the event of possible shocks.
Weight : 76 g
In this version, the oversize cage is only compatible with Shimano GRX 810-815 (2×11 speed) / GRX 812-817 (1×11 speed) rear derailleurs
We recommend a cassette of 34 teeth maximum for an optimal gear change for the GRX 810-815 version and a cassette of 42 teeth maximum for the GRX 812-817 version.
