The Box One Delta is an oversize 31.8mm stem designed specifically for BMX racing. Run with 31.8mm bars such as the Box Jet, Triple Taper Alloy or Box One Chromoly, it gives you the stiffest cockpit Box offer, which improves stability and control and puts more upper body power into your pedal stroke.

The body is extruded and CNC machined from 6061-T6 aluminium, and the top clamps are cold forged and CNC machined for extra stiffness and strength. Despite the girth, Delta stems weigh less than many standard 22.2mm stems. Extension comes in 48mm, 53mm and 60mm.

Features

31.8mm oversize clamp. The first modern oversize stem designed for BMX racing, so it pairs with 31.8mm race bars rather than standard sizes.
Stiffness you can feel. The added stiffness improves bike handling and turns more upper body power into forward momentum through the pedal stroke.
Three extension lengths. Pick 48mm, 53mm or 60mm to set your reach for the gate and the first straight.
Forged top clamps. Cold forged and CNC machined top clamps add stiffness and strength right where the bars are held.
Light for its size. Extruded and CNC machined 6061-T6 aluminium keeps the Delta lighter than many standard 22.2mm stems.
