A-Head Adapter Quill 1″ and 1 1/8″

A-Head Adapter Quill.

You would like to vary the handlebar height of your trekking or city bike fitted with a classic 1″ or 1 ⅛” threaded fork? Then the A-Head Stem Adapter Quill is a practical and technically elegant solution. Clamped in the fork shaft, it replaces the classic 1″ or 1 ⅛” shaft stem and offers a larger height adjustment range with a maximum of 70 mm retraction/extension. Perfect for adjusting the handlebar height to your physical needs and the type of your bike. With that, you can change the riding characteristics between relaxed-upright and sporty. The 60 mm clamping area of the robust aluminium adapter fits for 1″ or 1 ⅛” threaded forks and a threadless 1 ⅛” A-Head stem. The A-Head adapter is ideally combined with the matching by,schulz Stem Twist SDS or Stem Twist Pro SDS.
