Campagnolo over the years has offered 52/39 chainrings often. I have an Ultra Torque 52/39 10 speed crank that I bought years ago as an upgrade. In fact, I bought 2 of them as Campagnolo was clearing them out at bargain basement prices. I have since moved on to compact cranks which I now need since I am no longer as strong as I once was. I gave one of them to my son and have the other one in my storage room
