Prime 9 Technology is a counter-intuitive philosophy based on the less is more theory. It embraces range without adding complexity. The outcome is fewer parts, reduced weight, and increased durability.
Our Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform. The derailleur exploits our Limited Slip clutch technology without the Tri-pack features. 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!
