And for anyone that tries to mix and match Accushift and non-Accushift parts and expect a decent outcome...
The Accushift was excellent but the problems and negativity came from inept shops when they started to mix components, freewheels, chains, etc.. Suntour was clear from the service training, instructions bulletins in not deviating from the Accushift compatibility. There's some workable give and leeway by going outside of their compatible specs to Accushift but takes a bit more of understanding. Many shops were butchers and customers obviously didn't realize and trusted those shops. Shimano indexing got a better vibe and recognition from buyers.
Liked and still use both.
