I wouldn't worry too much, the bike and bars date from 2005...
When I looked closely at the break, the metal looks to have been starting to crack for a while and maybe I should have taken them out of the stem and checked.
Anyway I've just bought the same bar as NOS as I really like the shape and also have the same in carbon on another bike...
Agreed. With any vintage lightweight bars it's always worth keeping an eye open for crack formation.
On this particular bike I also upgraded to the same bar in carbon and relegated the alu to a beater...
