These purple axles mimic the design of authentic skateboard axles and incorporate a special locking mechanism known as the "inverted kingpin." This innovative system enables easier adjustment of the ride's hardness. Unlike traditional axles that rely on a nut, these axles utilize an inverted screw with a star-shaped head. This feature allows you to conveniently adjust the hardness using the provided tool, ensuring a secure fit and minimizing maintenance concerns or the risk of losing nuts. 
Compatible with all types of wheels
