Box Components Folding Tyre - 20"

Box One™ 120 TPI Folding Tires were engineered with a minimalist approach to hit lofty goals for weight, traction, rolling resistance, and rebound. At its heart is a super-supple 120TPI casing where we forced in as much rubber displacing nylon as possible. Skin walls are employed to reduce drag and further reduce weight. We flanked the high-density casing with a tightly packed hoop of aramid fibres. Finally, we draped this all with BMX race-specific tread that transitions from a centre band with a large contact patch to unidirectional tactile knobbies on the sides. This aggressive combination allows for maximum traction out of the gate, immense adhesion in the corners, and low rolling resistance in the straights. A state-of-the-art mixture of compounds is used in various areas of the apex, wall, bead seat, and centre – with higher silica content in the tread to again remove more weight.

Box Components Hex Lab Carbon Rim - 24"

All Hex Lab rims are engineered to be front and rear specific and crafted using Oversized Technology. Box have carefully studied the load paths from the bars through the stem, headset, fork, axle, hub to the spokes and into the rim for steering stiffness. The same approach was taken via the pedals through the cranks and other components on the way to the rear rim for pedalling stiffness. That extra stiffness will net you more power to the ground out back, and upfront, you'll feel in control. When combined with Box's other Oversized components, you'll experience heightened responsiveness and reduced latency. Due to their compatibility with tubeless and tubed configurations, these rims have a broad range of tire options and setup possibilities, making them perfect for any track. The Hex Lab Carbon BMX Rims are the only rims in the Box line-up to be blessed with Oversized Technology. They are also the only model to use Ultra High Modulus Carbon Fiber (stiffer than other carbons variants). Take notice of the unique Symmetrical Dihedral Angle Stabilizers. Yes, it’s a mouthful but each of those words carries meaning. The sculpted bullet-shaped spoke beds are designed to bridge the angle between the rim's angled flanks and the vertical plane. With that, we achieve the stability, stiffness, and durability of a much broader rim profile without actually taking on most of the extra material.

Box Components One Oversized Chromoly Handlebar

All Box ONE Chromoly handlebars are engineered and crafted using our Oversized Technology. Handlebars have a dual purpose as they contribute to both steering and pedalling stiffness. By strategically varying wall thicknesses and tube diameters, we have moved material from 3 low-stress areas to zones of high load. This has greatly minimised twist and contributed to responsiveness. Concurrently we have increased pedalling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar deflection and the consequences can lead to poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. This particular model handlebar is tailored for larger-sized racers and also takes our application of Oversized Technology one step further as it employs a tougher chromium molybdenum steel. This allows for a greater variation of wall thicknesses to combat the higher loads coming from that extra rider weight.

Box Components One Oversized M35 Crankset

All Box One M35 cranksets are engineered and crafted using our Oversized Technology. we all know that there is no use pushing hard on your pedals if you can’t deliver most of that power to the rear wheel. During the creation of our cranks, we were obsessed with Power delivery AKA pedalling stiffness. To reduce lateral deflection at the bottom bracket we chose to enlarge the spindle and the crank arm’s interfaces. We robbed material from unloaded sections to reinforce these zones of high stress. Not only are you going to be more efficient with power delivery, but you’ll also feel the instant response of acceleration. Seen through another lens, less energy will be required to achieve the same elapsed time. The Box One M35 crankset takes the oversized spindle action to an extreme with a colossal 35mm diameter cross-section courtesy of Praxis™. That dimension might seem massive, but we’ve also employed the use of cold-forged 7075 T6 aluminium. That's an alloy that delivers low mass but that also flirts with the toughness of steel. We then grind that spindle with the kind exactitude you’d expect from medical equipment. The very prominent crank arms are hollow-forged with much of the wall thicknesses pushed to high-stress zones. A stabilizer ring acts as an anti-twist brace between spider legs. A precision CNC-machined Chromoly/alloy self-extracting crank bolt system secures the package. Remember, you’ll need a modern frame to cope with this kind of technology.

The 24mm spindle is pressed into the drive-side crank arm for durability and easy installation. The non-drive side crank arm features a 2-bolt pinch system for added strength. The unique 4-bolt 104 BCD spider features a flex-resistant ring for optimum performance. Box Three Cranks feature steel pedal inserts that require pedal washers and externally sealed bearing BSA bottom brackets, both provided in the box.

Box Components Oversized M30-M Crankset

All Box One and Two cranksets are engineered and crafted using our Oversized Technology. We all know there is no use pushing hard on your pedals if you can’t deliver most of that power to the rear wheel. While creating our cranks, we were obsessed with Power delivery AKA pedalling stiffness. To reduce lateral deflection at the bottom bracket we chose to enlarge the spindle and the crank arm’s interfaces. We robbed material from unloaded sections to reinforce these zones of high stress. Not only are you going to be more efficient with power delivery, but you’ll also feel the instant response of acceleration. Seen through another lens, less energy will be required to achieve the same elapsed time. The Box One M30 crankset is just as tyrannical as its big brother the Box One M35. Since it's designed for the smaller rider the now 30mm spindle is as extreme to a smaller rider as the 35mm is to a burly world champion. The crank arms are hollow-forged but reduced in size for their application. It is possible to add too much stiffness that the rider will not feel the benefit. Going beyond that point simply adds material which is surplus weight. We’ve removed the stabiliser rings from the spider and removed unneeded material from its legs. These cranks are engineered for the smaller-sized racer. IMPORTANT NOTES: BB86 frames require Praxis™ part 86-4001B or 86-4001W. BB30/PF30 frames require Praxis™ part 68-4001R or 68-5401R. T47 frames require Praxis™ part 47-0000. Do not use pedal washers when installing pedals onto these cranks. M30-M cranks were designed to be used without pedal washers

Box Components One Oversized V-Brake 85mm

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 (mini-V) brakes are also an excellent choice for cyclocross or drop-bar gravel bikes. Box has 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. Box have 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.

Box Components Two Oversized 30mm Bottom Bracket

Several of the upper-tier Box bottom brackets were engineered using Box Oversized Technology. These were developed in concert with the crank sets. We all know that there is no use pushing hard on your pedals if you can’t deliver most of that power to the rear wheel. During the creation of our bottom brackets, Box were obsessed with Power delivery/pedalling stiffness. To reduce lateral deflection, we chose to oversize the bottom bracket and therefore subsequently enlarged the spindle and the crank arm’s interfaces. This made room for larger bearing rings contributing to a vast increase in contact area. Box removed material from unloaded sections to reinforce the zones of high stress. Not only are you going to be more efficient with power delivery, but you’ll also feel the instant response of acceleration. Seen through another lens, less energy will be required to achieve the same elapsed time.   Key differences: The Box Two M30 bottom bracket is a slightly less acute embodiment of our Oversized technology seen in the M35. Generously sized ABEC-5 bearings help reduce power loss to defection. The larger 30mm cross section is designed to mate up with the rest of the M30 line of Oversized cranksets.

Box Components Two BB Set 24mm

Box Two™ 24mm External bottom brackets feature cold-forged, CNC-machined alloy cups, dual-labyrinth bearing covers, and precision-sealed bearings.

Box Components Three Prime 9 Shifter

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).

Box Components Two Prime 9 Shifter

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 aluminium top shell but trades out the Box One's 1-piece pull-lever for a 2-piece resin and steel variant.

Box Components One DH 7 Speed Shifter

The Box One 7-speed Downhill multi shifter is packed with top of the line features such as a machined lightweight clamp, durable cast aluminum pull lever and top shell. Like the derailleur, it is also based on our 11-speed system, but here we have revised the internals for the rigours of its DH application.

Box Components Four 8S Wide Single Shift Groupset E-Bike Upgrade Kit

Our Box Four tier is for those people who just want less fuss! You're fond of Prime 9, but know 8 is enough, and surely 11-42T is plenty of range for an 8-speed cassette. Our derailleur still has the Limited Slip clutch but now arrives with a more compact cage. The custom 8-speed chain is built for abuse, although it's sophisticated enough to have its own Wide/narrow chainring. Push through fewer gears with a no-nonsense shifter. Ideal for E-Bikes

Box Components Three P9 Wide Multi Shift Groupset

The 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!

Box Components Two P9 X-Wide Single Shift E-Bike Groupset

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™ 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. The chain boasts the same unique ability to mate with a wide/narrow chainring except you give up the trick DLC top coat. You're hardly shortchanging yourself with Box Two.

Box Components One Prime 9 Chain

The Box One chain is protected by a dual-coating. Starting with a Nickel plating which aids in corrosion resistance and then top it off with the "Diamond-Like Carbon" layer. The DLC is as fancy as it sounds; a synthetic diamond nano-coating that turns up the volume on hardness, wear resistance, and slickness. All Prime 9 chains have chamfered shifting edges, solid plates and solid pins to safeguard durability. Our unique inner link spacing is engineered to grab those modern wide/narrow chainrings. Box has chosen to modernise the 9-speed platform due to the chain's spirited reputation.
