Box Hollow Mini Stem [ Colour : Black; Size : 45mm ]

Used by two-time World Champion Dane Morales, 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.

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.
