The GT NBS is a BMX stem for freestyle bikes with great value for money, and it is used to attach the fork to the handlebar. With the front load mount, you will get a bit lower bar height, a clean look, more stability and increased control. Due to the further bar placement from the rider, the front load design is a good choice for taller riders. This specific short 40mm reach is designed for 16'' and 18'' BMX bikes. The regular 22.2mm diameter makes this stem compatible with any regular sized handlebars.
