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.
