Tape Three Prime E-Bike 12-50

The Box Components Three Prime 9 E-Bike cassette features larger starting sprockets to increase resistance to the rigors of modern e-bike riding. The addition of an extra tooth to each of the first three sprockets offers increased durability and reduced wear by distributing force over a larger surface area. The Box Components Three Prime 9 E-bike cassette takes its inspiration from the cassettes in the Box One and Box Two ranges to achieve an excellent durability/quality/price ratio. All sprockets are made of steel, as is the structure that holds them in place. Its weight is kept to a minimum thanks to the presence of numerous holes on the sprockets.
