With precision sealed bearings and cold-forged, aluminum CNC machined cups, The Box One Titanium Square Taper bottom brackets are the best option for young BMX racers and other users of three piece cranks in search of performance gains and weight savings. They have hollow, custom titanium-nitride coated titanium spindles and carbon fibre center seals, helping keep the weight down between 185 and 190 grams. Other features include cups that are anodized black with anodized gold inner seals, and a JIS tapered spindle that comes in either 108 or 113 millimetres.
Box Two integrated headsets feature an aluminum top cap, CNC-machined bearing cover, and split crown race with super-smooth rolling, precision bearings. The 1.5" headset is designed solely for tapered frames and forks but also includes an adapter which allows you to run a straight 1-1/8" inch fork in a tapered head tube. It has a 45° x 45° upper bearing and a 36°x45° lower bearing.
Cold forged and fully CNC-machined from a number of high strength aluminum alloys, The Box One Stem Lock offers peace of mind and a level of added protection against losing your front wheel and fork legs in the event of a broken steerer tube. The stem lock runs through the centre of your steer tube providing compression for your headset and steering system. These are praticulary good for Carbon forks that use a carbon steerer tube and cannot accept a top cap or star nut. The Box One Stem Locks are backwards compatible with existing Box forks and may work with forks from other manufacturers.
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.
The Box Five cranks are a 3 piece alloy sqaure taper design, made with a durable cold forged construction from 6061 T-6 Aluminum. ###section### Product Specs Type:3pc Spindle Diameter:24mm Includes BB Bearings:No Weight:TBC ###shogun-image-section###
