Ultra-lightweight X Carbon bars are made using the world's best carbon fibre bicycle component technology. Designed for smaller BMX racers, they feature a unique profile that increases stiffness and strength, while keeping the weight low. Please note, the rider weight limit for these bars is 100 lbs. ###section### Product Specs Rise: Multiple Options Width: 21" Up Sweep: 2° Backsweep: 6 ° Bar Clamping Diameter: 22.2mm Bar Type: 2pc Weight: 162g - 3" 182g - 4.5" 285g - 6 ###section### ###shogun-image-section###
There is more to the carbon headsets than their exceptional good looks. From top to bottom, Box One Carbon Headsets have been designed to perform. Each unit features a custom CNC-machined alloy top cap in the shape of the Box logo with cut-outs to reduce weight. At the centre of the top cap is an anodised aluminium bolt that threads into a gold anodised aluminium expander plug. This expander eliminates the need for a star nut and works with all 1 1/8-inch steerer tubes—even carbon fibre steerer tubes. The top bearing cover is crafted from carbon fibre, which not only adds style but helps to 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. Box 1.5-inch headsets are designed solely for tapered frames and forks, but also include an adapter which allows you to run a fork with a straight 1 1/8-inch steerer tube.
Box One 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 and stiffness. By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, Box managed to reduce the weight and size and eliminated a serious hazard to the rider’s knees. To ensure proper clamping force, the stem must be mounted on a fork with at least 40mm of the exposed steerer tube. Please note, this stem is not compatible with carbon fiber steerer tubes. ###section### Product Specs TYPE: Front Load REACH: 55mm/60mm RISE: 0 CLAMPING DIAMETER: 31.8mm WEIGHT: 244 grams / 8.6 ounces (53mm)
Custom made from the highest quality 4130 chromoly, Box One Handlebars feature a proprietary 13-butted taper from 22.2mm at the grip area to 31.8mm across the lower bends. The added stiffness significantly improves bike handling while putting more upper body power into your pedal stroke. That means getting out of the gate and down the first straight faster and accelerating quicker out of the turns. ###section### Product Specs Rise: Multiple Options Width: 28.25" Up Sweep: 2° Backsweep: 7° Bar Clamping Diameter: 31.8mm Bar Type: 2pc Weight: 8: 753 grams / 26.5 ounces 8.5: 754 grams / 26.6 ounces ###section### ###shogun-image-section###

Box One Sprocket Bolt kits include five 8.5mm front bolts, five 6mm front bolts and five 5mm rear nuts so they will fit just about any sprocket/crank combination, including those with threaded holes.
Box One Single-Speed Cogs are CNC-machined from chrome-molybdenum and are designed to fit Shimano-compatible cassette hubs and have a 5mm wide inner base, giving a more solid connection to the cassette body. The chromoly cogs have an ED finish with laser-etched logos.
CNC machined from 6061-T6 aluminum alloy with laser-etched Box logos, Box One Schrader Valve Caps add a touch of style to any bike.
The Delta stem is the first, modern, 31.8mm oversize stem designed specifically for BMX racing. When used with the Box Triple Taper Alloy or Box One Chromoly (aka Maximus) handlebars, you get the absolute stiffest cockpit available. This added stiffness significantly improves bike handling while putting more upper body power into your pedal stroke, translating into more forward momentum. The Delta stem body is extruded and CNC-machined from the highest quality 6061-T6 aluminum. The top clamps are cold forged and CNC-machined for increased stiffness and strength. Despite their size and girth, Delta stems weigh less than many standard size 22.2 stems. ###section### Product Specs TYPE: Top Load REACH: 48mm/53mm/60mm RISE: 0 CLAMPING DIAMETER: 31.8mm WEIGHT: 299 grams / 10.5 ounces (53mm) E3
Featuring a heavily double-butted 14 gauge spoke (2.0/1.5/2.0mm) the Expert Spoke Kit is lighter AND stronger than traditional straight 15 gauge spokes. This is possible by using a spoke that is 14g at the ends but slims down 17g in the middle; this combination makes for an exceptional strength to weight ratio. Additionally included is lightweight black anodised aluminium nipples to further reduce rotational weight.
Box One's Front Load Race Stem boasts Cold-Forged and CNC machined 6061-T6 Aluminum Alloy construction for maximum strength and durability, with a Front-Load clamp design to fix those bars in place. Available in both 48 and 53mm extensions available it fits 1-1/8” steerer tubes and 31.8mm handlebars. ###section### Product Specs TYPE: 31.8mm REACH: 48-53mm RISE: 28mm CLAMPING DIAMETER: Front Load WEIGHT: 290g (10.2oz) - 320g (11.3oz)
Box One rims have a no-nonsense low-profile design that eliminates excess material, making them some of the lightest weight double-wall rims available. A 20 x 1.75 rim, for example, weighs just 362 grams/12.7 ounces. Strong and true, Box One rims have single eyelets to help prevent spoke pull-through, which means higher spoke tensions are possible. Available in 36-hole 20 and 24 x 1.75-inch, and 28-hole 20 and 24 x 1 1/8-inch sizes. Meets or exceeds ENBMX standards. Please note, Box One front rims lack a braking surface and are not designed to be used with rim brakes. Note: 99 lbs rider weight limit for 20 x 1 1/8" (451mm) and 24 x 1 1/8" (520mm) rims ###section### Product Specs WHEEL SIZE: 20" SEAM: Welded ERD: 391-512 HEIGHT: 14mm WIDTH: 17.5mm SPOKE HOLES: 28-36 WEIGHT: 20" x 1.75 (406mm): 295 grams/10.4 ounces 20" x 1 1/8 (451mm): 244 grams/8.6 ounces 24" x 1.75 (507mm): 400 grams/14.1 ounces 24" x 1 1/8 (520mm): 287 grams/10.1 ounces
