I'm looking for new lightweight handlebars. At this time I prefer aluminium, because of stiffness. ITM makes a lot of different models, The Bar seems to be the lightest and most expensive. Any experiences with this piece of equipment? How would it compare to the Four, the Millenium or the Cinelli Solida? those are all a bit heavier. Or should I just chose the Solida, to go with the Cinelli Grammo stem that I'm using (style over function!)?
