The Delta stem is the first, modern, 31.8 Ø, 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 stem bodies are 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. A 53-millimeter stem weighs just 299 grams.
Available with 48-, 53- and new 60-millimeter extensions in anodized red, blue, gold and black with laser-etched graphics and six chromoly bolts. Meets or exceeds ENBMX Category 1 standards. Delta stems only fit handlebars with 31.8 Ø clamp diameter.
