Kolobnev signs for Katusha

Controversial Russian rider Alexandr Kolobnev, who was cleared of systematic doping by the Court of Arbitration for Sport (CAS) at the end of February, has re-signed for Team Katusha for the remainder of the 2012 season. Kolobnev enjoyed plenty of success for Katusha in 2010 and 2011, though his final year with the team was blighted by accusations that he sold victory at the 2010 Liege-Bastogne-Liege to Alexandre Vinokourov.
