Box Three Prime 9 Cassette

The Box Three cassette draws from both its Box One and Box Two siblings to create a sensible all-rounder. All sprockets are stamped from steel and subsequently, the larger ones are pinned to steel spiders. The main difference here versus Box Two is the use of additional weight-reducing holes on the sprockets.
