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. Available as a multi-shift (pull several gears at once) or single-shift shifter (a sound choice for e-bikes).
$72.99 - $77.99
The Box Three E-Bike Cassette offers high gears with more teeth to withstand the rigors of modern E-Bike riding. Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! The Box Three E-bike cassette draws from both of its Box One and Box Two siblings to create a sensible all-rounder. All cogs are stamped from steel and subsequently, the larger ones are pinned to steel spiders. The main difference here versus Box Two is the use of additional weight-reducing holes on the cogs. FEATURES - Our Best All-Rounder Cassette - Steel Stamped Cogs - Steel Stamped Spiders - Ultra-Wide Ratio with Consistent Progression COMPATIBILITY - Box One Prime 9 Chain 126L DLC Black - Box Two Prime 9 126 Link Chain Nickel - Box Three Prime 9 126 Link Chain Polished - Box One Prime 9 Rear Derailleur - Box Two Prime 9 X-Wide Rear Derailleur Black - Box Three Prime 9 X-Wide Rear Derailleur Black - Box One Prime 9 Single Shifter Black - Box Two Prime 9 Single Shifter Black - Box Three Prime 9 Single Shifter Black

The Box One multi shifter is the only shifter on the market that comes factory stock with a hinged (and machined) clamp. It's top of the line and comes packed with other features such as a durable cast aluminum pull lever and top shell. 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. Available as a multi-shift (pull several gears at once) or single-shift shifter (a sound choice for e-bikes).

Box One Genius brake levers are the first ever to incorporate a clamp for ODI Lock-On grips. This ensures that your grips stay put while eliminating the need for an extra clamp. At roughly 50 grams, these cold-forged and CNC-machined levers beat any other on the market. Genius levers have a built-in return spring and are fully compatible with carbon handlebars. The Mid reach lever features a new design that puts it in the same reach position as the Long, but with a more BMX-specific blade for better one-finger leverage. Other features include adjustable reach, a titanium mounting bolt, and stainless steel hardware. Genius levers are designed to work with linear-pull brakes. They are excellent for BMX, mountain, city, urban, and tandem flat-bar bicycles.

The Box Two E-Bike Cassette differentiates itself from its non-e-bike sibling by offering high gears with more teeth to withstand the rigors of modern E-Bike riding. Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! All cogs are stamped from steel and subsequently, the larger ones are pinned to alloy spiders.

The Box One Prime 9 Rear Derailleur takes the advantages of our legacy 9-speed drive-train but adds the advancements of a modern 1 by; a fully adjustable Tri-Pack Clutch, and an x-wide cage optimized for an 11-50T cassette. Forged construction steps up the durability and performance to an unparalleled level. Suited for the most demanding terrain.
$209.99
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 or 11-50T and fashioned with steel 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!

All Box One forks are engineered and crafted using our Oversized Technology. These forks are the most important component in the quest for bike control. We’ve moved carbon from areas of low stress to areas that handle high loads. Those muscular shoulders aren’t just for looks as they are integral to achieving superior steering stiffness. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: This particular model fork is tailored for larger-sized racers. It also takes our application of Oversized Technology one step further as it includes a tougher 1-1/8 inch chromoly steerer tube and stiffer 20mm through-axle cold-forged dropouts. Weight Limit: 115kg (253 lbs) with limitations per Category 2 of EN 16054:2012 Standard. FEATURES - Oversized Technology™ - Chromoly Steel Steerer Tube to Accommodate Larger-Sized Racers - 20mm Through Axle to Increase Responsiveness - Internal Butterfly for Added Durability at Steerer Tube and Fork Crown Interface
