Cassetta Hope T-Rex Ratio Expander Sram

Descrizione

With this Hope Ratio Expander you change your Sram 11-36 cassette in an 11-40. Install the T-Rex behind your cassette and then leave one of the smaller sprockets out, usually the 17th.
By means of the specific design for Sram, Hope has been able to realize a perfect transition from the cassette to the expander. The shifting points and tooth profiles match precisely.
