The Box Three Prime 9 cassette is a great all-around cassette option. All cogs are stamped from steel and subsequently, the larger ones are pinned to alloy spiders. It also features weight-reducing holes on the cogs. - The Box Three Prime 9 offers ultra-wide ratio with consistent progressions - Prime 9 technology offers the same range as a 12-speed drivetrain, with fewer gears to shift through - Fewer parts, reduced weight, and increased durability - Cogs pinned to lightweight spiders - Constructed using a standard freehub body (HG) - Cassette Body Type: Shimano/SRAM 8, 9, 10 Speed - Drivetrain Speeds: 9 - Designed for ebike: Yes - Color: ED 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).

- Cold-forged, CNC-machined 6061-T6 aluminum with built-in return spring - Clamp integrates with ODI Lock-On grips - 50g

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 Three Rear Derailleur simplifies the features found on the Prime 9 Box One and Two rear derailleurs making for a fully featured wallet friendly rear derailleur. Including a Limited Slip Clutch, Sealed bearing pulleys and a solid construction Box Three Rear derailleurs are compatible with 11-46 and 11-50t derailleurs making it one of the most versatile derailleur offerings for Prime 9.

Hollow stems are cold forged from the highest quality 6061-T6 aluminum available. Featuring an open skeletal design and a dual mid-bolt wedge mounting system, they are lightweight yet maintain a very high level of strength. A 53mm extension stem weighs just 218 grams/7.7 ounces. By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, we reduced the weight and size and eliminated a serious hazard to the rider’s knees. These stems come with either a 48- or 53mm extension and a 22.2mm bar bore. To ensure proper clamping force, the stem must be mounted on a fork with at least 45mm of exposed steerer tube. Not compatible with forks that have carbon fiber steerer tubes.

Tested extensively by the Dutch National BMX Team, Damien Godet, Kory Cook, and numerous other elite racers, Box Two™ Freewheels combine durability with lightning-fast engagement. They feature nine, super durable pawls and are available in one of three choices -- 16, 17, or 18 teeth. To install, use the Park Tools™ FR-6 or other installation tool designed for single-speed freewheels with four notches that are approximately 32mm across measured inside to inside and 40mm outside to outside. FEATURES - 9 Pawls 108 [3.3°] Points of Fast Engagement

There is more to our carbon headsets than their striking good looks. From top to bottom, Box One™ Carbon Headsets was designed to perform. Each unit features a custom CNC-machined aluminum compression cap in the shape of the Box logo with cut-outs to reduce weight. At the center of the compression cap is an anodized aluminum bolt that threads into a gold anodized aluminum expander plug. This expander eliminates the need for a star nut and works with all 1-1/8-inch steerer tubes—even carbon fiber steerer tubes. The bearing cover is crafted from carbon fiber, which not only adds style but helps shave weight. At the heart of the headset are two super-smooth, titanium-nitride coated, sealed, 45×45 bearings. The titanium coating results in a low friction coefficient, increased corrosion resistance, and smoother rolling bearings. A split crown race makes installation and removal from forks super easy. FEATURES - Durable Titanium-Nitride Coated Sealed Bearings - Lightweight Non-Structural Carbon Components - Reusable Expander Wedge SPECIFICATIONS - Bearing Angle: 45° x 45° - Compression Cap: CNC-Machined - Bearing Cover: Carbon Fiber - Expansion Plug: Aluminum - Compression Cap: Aluminum - Finish: TiN Bearings - IS 42/28.6 - IS 42/28.6 - Weight 94 g / 3.3 oz

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. Due to its provenance, this is, without a doubt, the most durable cassette in the range and perfect for any E-MTB.

For Box braking we’ve limited the use of our Oversized Technology to the V area since the levers need to be minimalist and largely act as a remote for the V-Brakes. To reduce lateral deflection at the V we chose to enlarge the pivot areas and arms while tightening tolerances at their interfaces. We robbed material from unloaded sections to reinforce these zones of high stress. Not only are you going to be more efficient with brake power delivery, but you’ll also feel the instant response of deceleration. Key differences: The Box One V-Brake are the only brakes in the Box line-up to be blessed with Oversized Technology. They are also the only model to use sealed precision bearings to further reduce non-rotational movement. The 108mm long-reach brakes are excellent for BMX, mountain, city, urban and tandem bicycles using linear-pull-compatible levers. The 85-mm short reach (AKA mini-V) brakes are an excellent choice for cyclocross or drop-bar gravel bikes.
