  • R 500

Convert to a 1X10 setup easily with a Lyne 42T cassette expander. Our expander includes a free 16T steel sprocket to help smooth the gap where the 15 and 17T have been removed. This system allows you to use your existing Shimano or Sram cassette but increase the range to 42T as your largest gear. This can also be used to increase range on a 2x setup.
