Yes.
Older (than one-year-old) Veloce Ergopowers don't index the front shift, so
any front mech can be used with them.
In a few year's time those Veloce Ergos will be worth more than new ones, since they provide one of the few good ways of combining dropped handlebars with really low, i.e. mountain-bike, gearing that most tourists want.
