🔧 Why This Hubset Is So Good
 
Hand-built in Germany from aerospace-grade CNC-machined 7075 aluminum, this Tune hubset merges performance with precision. The Princess front hub uses a carbon-reinforced flange and pairs with the ClimbHill/KillHill rear hub that features Shimano Micro Spline compatibility. Equipped with sealed cartridge bearings and 6-bolt disc mounts, this set is durable, lightweight, and ready for serious road or gravel builds. Boost spacing adds structural rigidity, while Micro Spline ensures future-proof drivetrain compatibility.
