can anyone tell me what new size of bearings i need for it
Campagnolo can, it's in the manual. Which is at Campagnolo.com, that place I told you about earlier which hosts the manuals for stuff made by Campagnolo. I know it can seem confusing at first, but if you just remember that manufacturers often share their names with the websites which host all the relevant documentation, a world of possible not wasting our time opens up.
Of course there are, at Campagnolo.com
