I had the same bike and converted it to a triple and no you won't need a new rear or front derailleur.You will need to slide the front derailleur down closer to the 40 tooth ring (about a chains width gap or a little less) to account for the smaller 40 Tooth large ring. You may however need a different bottom bracket and I would just get one from Riv. You'll probably need either a 110mm or 113mm one. If the old one works without rubbing and it shifts your are good to go but the new sealed bearing units are nice and easy to install.
