The Box One Delta Stem represents a paradigm shift in front-end stiffness, being the first pro-level component specifically engineered for 31.8mm oversized handlebars. By pairing this top-load stem with Box One chromoly bars or triple-taper alloy bars, you create the most rigid cockpit in BMX racing. This CNC-machined 6061-T6 aluminum body, combined with a cold-forged top clamp, eliminates steering latency and ensures every watt of upper-body power is transferred to your pedals during gate starts. Designed for 1 1/8" steerer tube carbon forks and alloy frames, the Delta stem provides unrivaled track-ready stability while weighing less than many traditional 22.2mm stems.
