Box Three Prime 9 E-Bike Cassette

The Box Components Box Three Prime 9 E-Bike Cassette is designed for those who demand durability and performance from their E-Bike. With high gears featuring more teeth, this cassette is built to handle the demands of modern E-Bike riding. By adding an extra tooth to each of the three highest gears, it ensures increased durability and reduced wear, as the load is spread over a larger area.

This cassette combines elements from both the Box One and Box Two models, making it a versatile choice for riders. All sprockets are crafted from steel, with the larger ones attached to steel spiders for added strength. A key difference from the Box Two is the inclusion of additional weight-reducing holes on the sprockets, making it lighter without compromising on strength.
