I have an old Trek 830 mountain bike that I've been fixing up as a second touring bike. I keep it at our beach house on the south coast of Spain and use it for rides in that area and into Portugal. I want to put a good-quality front rack on it, either Old Man Mountain or Tubus, both of which are available here in Seville. The problem is I don't know which of the racks made by those companies will fit it. I'd prefer to have a low-riding model.

Any ideas on which racks might fit this old bike?
