BOX Delta Stem

The Delta stem is the first, modern, 31.8, oversize stem designed specifically for BMX racing. When used with the new BOX Maximus chromoly handlebars (currently the only BMX bars on the market compatible with the Delta), you get the stiffest cockpit available. The added stiffness significantly improves bike handling while putting more upper body power into your pedal stroke and therefore, forward momentum.

 The stems are CNC-machined from the highest quality 6061-T6 aluminum. And despite their size and girth, weigh less than many standard size 22.2 stems. A 53-millimeter stem weighs just 285 grams
