Box Two Threadless Headsets have an aluminum top cap, upper bearing cover, lower race and upper and lower cups. All-aluminum construction results in a lightweight yet durable headset. Each headset is fitted with super-smooth rolling, precision, angular-contact sealed bearings.
Box Two Chain Tensioners let you dial in your chain tension so it's just right. Two mounting holes provide room for ample adjustment on most frames. When used properly, Box Two Chain Tensioners help protect frame dropouts and keep your rear wheels locked in place where they should be. For use with 10mm axles only.
Box One's Race Linear Brake Cable is built specifically for BMX-racing and the stresses and strains the brakes are put under. It all starts with custom cable housing that features stainless steel mesh-wrapped linear wires for the best combination of braking and cable strength. The inner cable wires are stainless steel so they won't rust over time.
Box Two Quick Release Seat Clamps are cold forged and CNC machined from 6061-T6 aluminum alloy. Weighing in at just 27 grams/ 0.95 ounces in the 31.8 size, they are as lightweight as they are tough. The head of the quick release lever and the face of the clamp are given a proprietary low-friction surface treatment that ensures smooth lever action for the life of the clamp, without the need for a bushing. Meets or exceeds ENM standards.
The Box Two Hollow Center Clamp stem is 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 218g/7.7oz. By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, Box reduced the weight and E3size and eliminated a serious hazard to the rider’s knees. These stems come with either a 48mm or 53mm extension and have a 22.2mm clamping diameter. 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. ###section### Product Specs TYPE: Front Load REACH: 40mm/45mm/48mm/53mm RISE: 5mm CLAMPING DIAMETER: 22.2mm WEIGHT: 218g/7.7oz (53mm) E4
