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 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.  

Box Components Five Square Taper Crankset

Featuring a JIS square taper standard, oversized bottom bracket interface, which showcases a step-down shape specific to the crank arm-length meeting at the pedal boss. Unlike alternative options, no two lengths are the same. These durable cold-forged cranksets are available in sizes from 135mm through 170mm and employ a 5-bolt 110 BCD chainring pattern. All JIS square taper standard cranks are compatible with all BSA European-style square taper bottom brackets  

Box Components Four 2-Piece Crankset

The Box Four Crankset features a 2-piece design with an oversized bottom bracket interface. 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. Our unique 4-bolt 104 BCD spider features a flex-resistant ring for optimum performance. Box Four Cranks feature steel pedal inserts that require pedal washers and external sealed bearing BSA bottom brackets, and both are provided in the box. Weight Limit: 115kg (253 lbs) with limitations as per Category 2 of EN 16054:2012 Standard

Box Components Three Hollow Forged Crankset

The Box Three Crankset features a hollow-forged 2-piece design with an oversized bottom bracket interface. 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 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
