It is a model that can be installed on the new Shimano R91xx/R80xx (11 speed) series.

(1) Equipped with a CDJ original pulley that uses AURUM+CF30 next-generation resin (super engineering plastic). It has a high strength comparable to that of aluminum but is super lightweight with only about half the weight. Excellent sliding resistance and significantly improved quietness.
②Newly designed narrow wide guide pulley 14T and tension pulley 18T. The uniquely developed tooth tip shape fits perfectly into the holes that make up the chain. It is a big pulley with excellent shifting performance, so it can be used with confidence.
(3) A new cage design was designed after determining the appropriate position for the larger tension pulley.
④6 colors (matte, clear, red, blue, yellow, green) pulley cage finish allows you to choose the coloring that matches various bikes.
⑤Supports rear cassettes up to 34T. [It is essential to adjust the end bolts in balance with the chain length]
