🔧 Why This Hubset Is So Good
 
Hand-built in Germany from aerospace-grade CNC-machined 7075 aluminum, this premium hubset offers a perfect blend of strength, stiffness, and weight savings. The Princess front hub and ClimbHill/KillHill rear hub both feature CenterLock disc mounts and Boost spacing, giving superior lateral wheel stiffness. The rear hub’s Micro Spline freehub supports Shimano 12-speed for future-proof gear compatibility. Sealed cartridge bearings and a three-pawl ring keep spin smooth and maintenance minimal. Total set weight is impressively low at approximately 328 g.
