Groups 12-42 Single-Shift E-Bike

The group Box Components Four 8-speed 12-42 is designed for those who just want less hassle! You like the Box Components Prime 9, but also know that 8 speeds can be enough, and that 12-42T is certainly a sufficient range for an 8-speed cassette. The Box Four derailleur benefits from the Limited Slip clutch, which reduces chain clatter, and a more compact clevis that will be particularly appreciated on children's bikes. The specific 8-speed chain is designed for abus, although it is sophisticated enough to be compatible with narrow/wide chainrings. The group Box Component Four 8-speed will take you to the single chainring at lower cost.
