Product Description
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.

CONSTRUCTION
BMX Handlebars come in either a 2 piece construction or a 4-piece construction. What one you choose is down to personal preference. 4-piece bars offer additional strength (and weight) and are popular mostly with Street riders. 2-piece bars offer a more classic look and are typically lighter.

The rise refers to how tall the bars are, and is the biggest influence on how your handlebars will feel. The rise of the bars is completely down to personal preference. If you are starting from scratch and need a reference point, then handlebars with a rise of 8"-8.75" are considered average.
This angle measures how much the bars angle upwards at the grip area. A 0˚ up sweep would mean that the grip area is perfectly flat and parallel to the ground. The up sweep angle choice is completely down to rider preference with the average being between 2˚ - 3˚.
The width of handlebars simply refers to how wide the handlebars are - they typically range from around 27" to 30" in iwdth. Again this is completely down to personal preference and many riders cut the bars down to a required width if needed with a hacksaw.
Back sweep refers to the amount the grip area of the bars angles back towards the rider. This angle plays a pivotal part in how the handlebars feel. A 0˚ back sweep would mean the bars are completely flat, the larger the angle the more the bars angle back. An average back sweep would be between 2˚ - 3˚.
