Workington Comets have signed former Newcastle Diamonds rider Rene Bach and Cumbria-based Gary Irving to their line-up for the 2012 season.
Bach, 21, won the Premier League play-offs and Premier Trophy with the Diamonds in 2010, and will double up with Elite League side Peterborough.
"We are very happy that he has agreed to join the Comets for 2012," said promoter Keith Denham.
"Gary really impressed us with his commitment in 2011."
Denham added: "He is a genuine out-and-out racer who is proud as a Cumbrian to ride for the Comets, and I am genuinely pleased to be able to announce Gary as a member of the team."
