I'd say, if you're going to race your bike, pick up a lighter set of wheels if you wish, but if you're just training it's not worth the cost to get lighter wheels. Sure, they're lighter and all but the Racing 1's aren't really designed for training.
I have the Racing 1's on my Tarmac Pro but I don't train on them. In fact, I don't train on my Tarmac at all. It's strictly a race bike. I train on a 853 steel framed, Ultegra equipped bike with heavy Mavic wheels.
So, what are your intentions? Ask yourself that before spending the money.
