Box Components Tape Two Prime E-Bike 12-50

The Box Components Two Prime 9 11-50 cassette features steel sprockets held together by a 7075-T6 aluminum structure for a good compromise between lightness and strength. The Box Compnents Two cassette was the model where the Prime 9 groupset began. Designed atorigine as an E-MTB product to offer long life and extra range on fewer gears, this technology was then transposed to muscle mountain bikes.
