🔧 Why This Hubset Is So Good
 
The Tune Prince/Princess Boost hubset is hand-built in Germany and engineered for precision, durability, and ultra-low weight. With CNC-machined 7075 aluminum bodies and a carbon-reinforced non-disc flange on the Princess front hub, this set is ideal for high-performance mountain and gravel builds. The 6-bolt disc interface is easy to maintain and compatible with a wide range of rotors. The rear XD/XDR freehub accommodates SRAM cassettes. With 28 spoke holes front and rear, this hubset offers strength and build flexibility while keeping things super light.
