🔧 Why This Hubset Shines

Hand-built in Germany from aerospace-grade CNC-machined 7075 aluminum, this top-tier hubset combines precision engineering with race-ready performance. Both front and rear hubs feature Boost spacing [15×110 mm front, 12×148 mm rear] and reliable sealed cartridge bearings. The rear hub employs a Shimano Micro Spline freehub, ensuring compatibility with current 12-speed MTB drivetrains and HG/road 9–11 speed cassettes. A robust, low-weight design [around 356 g with 32h] comes from straight-pull flange profiles and 6-bolt disc rotor mounts.
