    About This Product

    Did you know that you can mix and match Prime 9? Can't decide between the modern basics of Box Three and the long service life of Box Two? Well, you don't need to! With this pre-configured and pre-tested option, you'll receive a Box Three cassette and chain paired to the durable Box Two derailleur and shifter. INCLUDES Box Two Prime 9 Multi Shift Shifter Box Two Prime 9 X-Wide Rear Derailleur Box Three Prime 9 11-50T Cassette Box Three Prime 9 Chain Box One Shift Cable & Housing Kit Our Box Two tier's mission in life is to deliver performance similar to the Box One but without its exotic (and costly) features. You still get the Tri-Pack (TM) Clutch in our derailleur only it isn't adjustable. The cassette's 11-50T range is equally impressive but we don't cut it out of a single block of steel. The action on the shifter is just as snappy although you don't get the rigid die-cast pull lever. Our Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform. Cassettes are accessible at 11-46T and fashioned without spiders. The derailleur exploits our 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!
