His twin brother is Vladimir Efimkin. Alexander Efimkin burst on to the professional cycling scene in 2005 with a 2nd place overall at the Settimana Ciclistica Lombarda, a highly competitive race.

In part this is owing to his service to the stars of his team, and in part due to his relatively young age.
