The Italian BMC rider, who won the 2008 world title on home soil and the Tour of Flanders the previous year, is one of several former and current Lampre team riders and staff associated with a doping investigation in Mantova, Italy.
The Italian Anti-Doping Tribunal found him guilty of violating article 2.2 of the World Anti-Doping Agency code relating to the "use or attempted use of banned substances".
He had been provisionally suspended by BMC - whom he joined in 2010 - in April that year but was allowed to return to action the following month when the investigation seemed to stall.
Also involved in the review are pharmacist Guido Nigrelli, who was banned for life, and physician Fiorenzo Egeo Bonazzi, who was handed a four-year suspension.
