Birmingham Brummies have signed three-times British champion Chris Harris from Midland rivals Coventry Bees.
'Bomber' Harris, 31, will replace the departed Bjarne Pedersen as the new number one for the Brummies, who had to beat off three rival clubs to sign him.
"Chris is the type of rider we want," said joint-team boss Phil Morris. "The fans can be assured he will give 100% to the Brummies. He's fully committed."
Harris's signing come on top of Danny King agreeing a third straight season.
"I'm very pleased to be a Birmingham rider once again in 2013," said the Brummies skipper. "It's a very well-run club with professional management. I'm looking forward to another shot at the play-offs."
Brummies co-promoter Graham Drury added: "Danny is a reliable rider who very rarely let's you down.
"He's popular with his team-mates and popular with the fans so it was the logical thing to do to bring him back for a third season."
Pedersen has moved back to his former club Eastbourne, for whom he rode in 2011, after a troubled campaign with the Brummies.
"This year was one of my worst seasons ever," he said, "I just want to get back to my best. There were five other clubs calling me but it was quite an easy decision."
Despite the loss of Chris Harris, Coventry captain Scott Nicholls has agreed terms to remain with the Bees next season, one of four confirmed Bees starters in 2013, along with Aaron Summers, Adam Roynon and Michal Szczepaniak.
The seven-times British champion enjoyed a consistent campaign in 2012, despite being hampered by a mid-season lay-off with a broken collarbone.
