Jamis-Sutter Home announced today that it has signed Tom Zirbel for the remainder of the 2011 season. The time trial specialist will participate in a full National Racing Calendar (NRC) with the team and might be eligible to start the UCI 2.HC Amgen Tour of California from May 15-22.
"I am very excited to join the Jamis/Sutter Home squad," said Zirbel in a press release. "I have tremendous respect for DS Sebastian Alexandre and appreciate the support that Jamis and Sutter Home have been providing to the sport for so many years."
Zirbel could be a candidate to compete in the Amgen Tour of California, having placed in the top ten in the event’s time trial in 2008 and 2009.
Race organizers, AEG Sports, announced a rigorous anti-doping protocol in February. The protocol required teams to present a preliminary roster of 12 riders that were added to the anti-doping testing pool on February 15. Those riders were to be tested for 90 days prior to the event’s start date on May 15. Team management were then required to select a final roster of eight riders from the original 12 riders registered in the testing pool.
However, AEG President Andrew Messick said he would handle requests to add riders to team rosters after the February 15 deadline on a case-by-case basis. According to Alexandre there is a possibility that Zirbel might be permitted to start the race, however, that will not be confirmed until a later date.
"Tom is recognized as one of the best time trialists in the world," said Alexandre. "We are very excited that he will be riding in Jamis/Sutter Home colors this season."
The US Anti-doping Agency (USADA) gave Zirbel a two-year suspension after he tested positive for Dehydroepiandrosterone (DHEA) at the US Pro Championships on August 29, 2009. USADA reduced his suspension by six months, ending on March 21, 2011, for helping the agency in two separate anti-doping cases. He maintains that he did not knowingly ingest the banned substance.
