Cipo said to have signed with Rock Racing

The on-again, off-again relationship between Mario Cipollini and Michael Ball's Rock Racing team seems to be on again. La Gazzetta dello Sport reported Sunday that the Italian sprinter had signed with the American Continental team and will ride the Tour of California next month.

The 40 year-old former World Champion has 42 stage wins in the Giro d'Italia and 12 in the Tour de France. He also has tax evasion fees of 1.1 million Euros from the Italian government.
