Simple to install the Ranger 40 spocket to increase the range of your existing cassette. Just slide it your cassette and you are set to take advantade of the benefits of a 1 x 10 wide range setup. To make room for it, you will have to remove one of the single sprockets.
The Ranger 40 is designed to fit both Sram and Shimano cassettes with use of a spacer. The Ranger is compatible with many 10 speed cassettes in the market, see image above. Also included is a replacement B tension screw to make adjustment easier. For best performance in a 1 x 10 setup, we advise using a mid length cage deraillerus.
