What Is Prime - 9?PhilosophyPrime 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.Why Not 12?9 Is FineAs a newcomer to the drivetrain market, we didn’t see the need to follow convention. Adding range doesn’t require the addition of gears. Why not enjoy the range of a 12 speed with 9.Why Is 9 Fine ?DurableLess aggressive chainline vs. a 12-speed system. Be prepared for less system wear and tear.SimpleAll those clicks add up. Spend less time shifting and more time in the right gear.LightFewer cogs on the cassette reduce system weight.

Box Two Quick Release Seatclamps are cold forged and CNC machined from 6061-T6 aluminium alloy. A quick release lever makes seat height adjustments a snap.Size 31.8mm.
Tri-pack™ ClutchFine tune input at the shifter and set chain tension accordingly with Tri-Pack™ Clutch technology. This advanced chain retention system provides instant engagement and long-lasting chain dampening throughthe use of a one-way roller bearing and composite friction plates. Housed in the lower knuckle, TriPack™ is both user-friendly and easy to maintain, allowing riders to adjust clutch force* with a simpleTorx® -equipped multi-tool.Forged ConstructionImpact resistance is greatly improved by way of forging — a key manufacturing process that strengthens critical components. Tested at the premier freeride event of the season -- Red Bull® Rampage-- this new construction has proven itself capable of performing at the highest levels and comes standard on all second-generation Box derailleurs.Pivot-tech™Impact resistant, spring-loaded cable stay keeps cable, housing & you out of harm’s way.
The Box Two shifter is the only shifter on the market (other than our Box One) that comes factory stock with a hinged clamp. Box Two is our performance tier so this shifter still maintains the durable cast aluminum top shell but trades out the Box One's 1-piece pull-lever for a 2-piece resin and steel variant.All Prime 9 shifters take advantage of the 9-speed's inherent durability, simplicity, and reliability. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. And the best part is? Prime 9 is also terribly forgiving so you won't have to constantly adjust your set-up.
Box Two Headset Adapters allow the use of 1-inch threadless headsets and forks with 1-inch steerer tubes in frames designed for standard, 1 1/8-inch threadless headsets. Please note: this adapter is not designed to be used with integrated headsets.
Box Two Chain Tensioners let you dial in your chain tension so it's just right. Two mounting holes provide room for ample adjustment on most frames. When used properly, Box Two Chain Tensioners help protect frame dropouts and keep your rear wheels locked in place where they should be. For use with 10mm axles only.
Box Two Threadless Headsets have an aluminum top cap, upper bearing cover, lower race and upper and lower cups. All-aluminum construction results in a lightweight yet durable headset. Each headset is fitted with super-smooth rolling, precision, angular-contact sealed bearings.
Box Two integrated headsets feature an aluminum top cap, CNC-machined bearing cover, and split crown race with super-smooth rolling, precision 45°x45° bearings. Please note: this particular headset is designed to allow the use of 1" forks with frames that have 1-1/8" integrated head tubes.
Box Two integrated headsets feature an aluminum top cap, CNC-machined bearing cover, and solid crown race with super-smooth rolling, angular contact bearings.

Box Two integrated headsets feature an aluminum top cap, CNC-machined bearing cover, and split crown race with super-smooth rolling, precision bearings. The 1.5" headset is designed solely for tapered frames and forks but also includes an adapter which allows you to run a straight 1-1/8" inch fork in a tapered head tube. It has a 45° x 45° upper bearing and a 36°x45° lower bearing.
