Superior craftsmanship: The high-strength steel springs of the spring-loaded seat post provide robust support, retain their shape and are rust resistant. With a lifespan of over 2 years, these springs last much longer than conventional ones. The seat post is manufactured using forging technology, which ensures exceptional quality and long-lasting durability and provides cyclists with a first-class riding experience.

The 3.0 mm spring is already mounted on the seat post, and two additional 2.8 mm springs are included to ensure optimal shock absorption for each user.
Easy installation and adjustment: Simply tighten a screw to connect the spring-loaded seat post to the saddle, which is faster and more comfortable compared to similar products. This greatly saves installation time and allows users to quickly enjoy their driving experience.
