The Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform. Cassettes are fashioned with steel spiders. The derailleur exploits Box's Limited Slip clutch technology without the Tri-pack features. Shift easily with a comparable mechanism, 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!
