RT0-Q02F Ring brake quick release highway car flower drum

The core selling point of this lightweight and high-strength ring brake drum is its dual-mode compatible design of "quick disassembly of the ring brake+upgrading of the side cover to a 12mm cylinder shaft". Outstanding market advantages: dual-use, covering both old circle brake road vehicles and new cylinder axle frames, reducing user upgrade costs, extending product lifecycle, and highly attractive to both vehicle brands and DIY players. In terms of features, lightweight and high strength are equally emphasized, and the quick release structure is convenient for daily maintenance and wheel replacement. By replacing the side cover, the 12mm cylinder shaft can be switched, improving rigidity and installation accuracy, and compatible with mainstream disc/ring brake hybrid requirements. The application scenarios include upgrading ring brake road bikes, Gravel and commuting training wheelsets, as well as cycling enthusiasts who need to adapt to multiple chassis with one drum. In short, it is a cost-effective flower drum that balances lightweight, strength, and cross specification compatibility.
