Here is another extremely rare item…a new-old-stock (NOS) Suntour Accushift Plus 7-speed cassette that includes a 13-15-17-20-23-26-30 cluster. These models were one of Suntour’s mid-range offerings in the early 90’s for 7-speed cassettes (around the 1990 and 1991 time period). Additionally, because of the taller gears, they were primarily marketed with mid-range mountain bike components (i.e., the Suntour XCD group, etc.), but their specs are the same as higher-end models, so they should mount fine on other 7-speed (non Micro-Drive) Suntour freehubs.
These cassettes are index (or as Suntour used to call it, “Accushift Plus”) shifting capable. Also, please note this is a cassette (and not a freewheel), and it will only work with a Suntour splined hub (and will not work with any threaded rear hubs or Shimano’s more popular splined hubs, as the splines are different sizes).US $99.99
