Box Components Hollow BMX Stem

By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, we reduced the weight and size and eliminated a serious hazard to the rider’s knees.

The BOX Hollow BMX Stems come with a 48- or 53-millimeter extension and a 5-degree rise or drop.

To ensure proper clamping force, the stem must be mounted on a fork with at least 40 millimeters of exposed steerer tube.

Available in Anodized Red, Blue, Gold and Black with laser-etched graphics and six hollow chromoly Allen bolts. Meets or exceeds ENBMX Category 1 standards. Fits 22.2 Ø handlebars. Not compatible with carbon fiber steerer tube forks.
