Used by two-time World Champion Dane Morales, the BOX Mini Hollow Stems are cold forged from the highest quality 6061-T6 Aluminum. They also feature an open skeletal design and single mid-bolt wedge mounting system, making them among the lightest weight mini stems on the market. A 40-millimeter extension stem weighs just 132 grams grams/4.6 ounces.

The Mini Hollow stems have a single-bolt wedge clamp, meaning there is no rear-facing pinch bolts to injure the rider’s knees. They come with a 40- or 45-millimeter extension.

To ensure proper clamping force, the stem must be mounted on a fork with at least 28 millimeters of exposed steerer tube.

Available in Anodized Red, Blue, Gold and Black with laser-etched graphics and five hollow Chromoly Allen bolts. Meets or exceeds ENBMX Category 2 standards. Fits 22.2 Ø handlebars. Not compatible with Carbon Fiber steerer tube forks.
