A258R Six nail dead flying field car rear flower drum

A258R is an advanced upgraded version of the popular A239R. It perfectly inherits the double-sided flywheel design of "dead flying on one side, active flying on one side", allowing riders to seamlessly switch between commuting and racing without changing wheels. Its biggest core selling point lies in the innovation of the dead fly tooth installation method - adopting a six nail locking structure, completely replacing traditional threads. This design significantly enhances the torque resistance and bite strength of the teeth, making them less prone to loosening or slipping during intense pedaling or high-frequency Skid braking, significantly improving safety and durability. Black anodized coating gives a more hardcore feel. Specially designed for high-intensity track racing, street gear fixing players, and urban commuters. The active flying side is suitable for easy daily gliding, while the six nail dead flying side can withstand violent riding and extreme braking.
