Harris Custom 9-spd Cassette, 12-32 HG-61 Big Dozen
12 - 13 - 14 - 16- 18 - 21 - 24 - 28 - 32 Teeth
Custom 9-speed touring cassette by Sheldon Brown
Based on the HG-61 series Shimano cassette.
It is generally good practice to replace the chain when you replace the cassette.
We recommend the SRAM PC-951 chain for use with this cassette.
This cassette will index with any Shimano-type 9-speed shifter, but will require a medium (GS) or long-cage (SGS) rear derailer due to the large bottom sprocket. Pretty much any rear derailer designed for use with a triple chainring should work.
