The Box Four shifter's main features aren't strikingly different from Box Three's. The key difference is its 8-speed platform. We've chosen to modernize the 8-speed in much the same way we did the 9-speed for Prime 9. Just like the Prime 9, the Box Four shifters take advantage of the "less is more" theme and exploit durability, simplicity, and reliability. Available as a multi-shift (pull several gears at once) or single-shift shifter (a sound choice for e-bikes). -Our 8 is Enough Shifter -Lightweight Extruded Clamp -Responsive 2 Piece Pull Lever -MTB Style Release Lever (V2) Weight: 128g/4.5oz

The Box Three shifter makes good use of nylon composites in both top and bottom shells as well as the levers. Box Three is our performance and value tier. So this shifter sheds all the fancy trappings of the top 2 tiers but maintains their shifting characteristics. 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).
$51.99
The Box Four cassette adapts our Prime 9 philosophy of durability, simplicity, and reliability at a great price point.

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).

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!

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.

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
