1. Adjustable suspension bar: This bicycle handlebar has a 7° increase design that can be adjusted according to your preferred angle, so you can find the perfect riding position. 2. Reduce Vibration The material stem achieves a near straight parallel movement relative to the ground, effectively reducing high frequency vibration from the handlebars on uneven terrain, ensuring a smoother and more comfortable ride. It helps relieve back, neck, wrist and shoulder discomfort. Spring bars help relieve discomfort by absorbing shock and vibration, ensuring a more comfortable driving experience. 3. Four link design: Equipped with a fourlink design, this stem allows the handlebar to 'float' relative to the ground, maintaining a consistent grip position while driving and ensuring uncompromising control and steering. 4. Adjustable Softness With four different soft and hard springs, you can adjust the suspension to your riding style. The outer elastomer can be replaced with an 8mm hex wrench, providing different levels of comfort and performance.
