Box Three Prime 9 X-Wide Single-Shift 9-Speed E-Bike Groupset

The Box Three tier delivers many of the same capabilities as its more famous siblings yet it's built upon a simpler platform. The cassette is E-Bike optimised at 12-50T, adding an extra tooth to each of the three highest gears. The derailleur exploits Box's Limited Slip clutch technology without the Tri-pack features. The action on the shifter is limited to one downshift per lever swing, although you'll forgo the hinged clamp and die-cast structure. And lastly, string it all together with a Prime 9 chain but without extravagant coatings. If you're looking to bring your 2/3 by bike into the 21st century, then level up with this group!
