Box Components 12-42 Single-Shift E-Bike

The Box Components Four 8-speed group is designed for those who simply want less hassle! If you like the Box Components Prime 9, you’ll also know that 8 gears can be sufficient and that a 12-42T range is certainly adequate for an 8-speed cassette. The Box Four shifter benefits from the Limited Slip clutch, which reduces chain chatter, and features a more compact fork head, which will be particularly useful for children's bikes. The special 8-speed chain was developed for this system, although it is so well-designed that it can be used with Narrow/Wide chainrings. The Box Components Four 8-speed group offers you an affordable way to a single chainring setup.
