Box Components + Professional Installation
The Box Four tier is built for riders who want simplicity with solid performance. If you like the idea of Prime 9 but don’t need all nine gears, this 8-speed setup delivers plenty of range with a 12–42T cassette. The derailleur still features the Limited Slip clutch, now paired with a more compact cage. A tough custom 8-speed chain and dedicated wide-narrow chainring handle serious use, while the straightforward shifter keeps things simple with one downshift per lever swing.
INCLUDES
- Box Four 8 Speed Single Shift Shifter
- Box Four 8 Speed Wide Rear Derailleur
- Box Four 8-Speed 12-42T E-Bike Cassette
- Box Four 8 Speed 116 Link Chain Natural
