Ihaga S.A.G.

Ihaga SAG derailleur main image

I rather like this Ihaga S.A.G.:

  • I like that it is Belgian - variety is the spice of life.
  • I like the high quality of construction and finish.
  • I like the way the pulley wheel has a large inner flange that rotates along with it.
  • I like the thick chrome and black look.
  • I am tantalised by the mystery of the meaning of ‘S.A.G.’.
  • But, above all, I like the fact that is top-normal in an age that was dominated by low-normal designs.

This last feature is achieved by a cunning cable routing that involves a roller - best understood by looking at the diagram in the instructions.

In the photograph I have disengaged the main spring to allow the derailleur to take up a more normal position.
