Achieve perfectly aligned headset bearing seats in a single operation. The Unior head tube reamer and facing tool for 1 1/8" head tubes combines reaming and facing in one setup, ensuring bearing cups seat squarely and rotate smoothly — essential for precise steering feel and long headset life.

  • Reams and faces the head tube in one operation, saving workshop time
  • For 1 1/8" head tube standard — the most common size across road, MTB, and gravel frames
  • Precision-ground cutters ensure square, parallel bearing seats
  • Rigid construction maintains alignment throughout the cut
  • Professional Unior quality for workshop accuracy and durability

Misaligned or unfinished head tube bearing seats cause premature wear, creaking, and poor steering precision. This combined reamer and facer removes material evenly to produce the correct bore and face angle simultaneously, giving headset cups a true, flat seat to press against.

Designed for 1 1/8" head tube diameter. Suitable for use on aluminium and steel frames in a professional bicycle workshop setting.
