Abstract
This utility model relates to the field of quick-release droppers for bicycle thru-axles, and discloses a quick-release dropper for bicycle thru-axles, including an upper thru-axle portion. The upper thru-axle portion has a positioning boss inside, and a positioning groove is formed on the top of the positioning boss. The bottom of the upper thru-axle portion has a lower dropper handle portion, and a quick-release rod guide groove is formed on the outer wall of the lower dropper handle portion. Through a height adjustment component, when the user presses the limiting block, the spring is compressed, causing the limiting block to disengage from the positioning hole. At this time, the user can easily slide the positioning boss up and down. When the positioning boss moves to the target height and the limiting block aligns with the new positioning hole, the spring force instantly pushes the limiting block to precisely engage in the hole, achieving multi-level height locking of the positioning boss. This design can accurately adapt to forks of different thicknesses, ensuring coaxiality and stability during wheel installation, and is convenient to operate and reliable in locking.
