The Box Components Four 8-speed 11-42 group is designed for those who simply want less hassle! You may like the Box Components Prime 9, but you also know that 8 gears can be sufficient and that an 11-42T range is certainly adequate for an 8-speed cassette. The Box Four derailleur benefits from the Limited Slip clutch, which reduces chain slap, and features a more compact derailleur head, making it particularly appealing for children's bikes. The special 8-speed chain was developed for Abus, although it is mature enough to be compatible with narrow/wide type chainrings. The Box Component Four 8-speed group offers a cost-effective solution for a single chainring setup.
