BOX MTB Box Three Prime 9 E-Bike Cassette Black

The Box Three E-Bike Cassette offers high gears with more teeth to withstand the rigours of modern E-Bike riding. Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! The Box Three E-bike 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.
