9-Speed Elite Cassette (Shimano/SRAM) (Extra-Wide Range 12-40t)
Item# 30870

Product Description

Maybe not tight enough shift to shift for picky racers, but if you are just after range, here you go. Should work with most MTB rear derailleurs, but a Wolftooth Goat Link may help. Lightweight alloy spider holds the two largest cogs. 12-13-15-17-21-25-28-34-40t Shimano/SRAM-compatible.
