Second time round for local boy
The 25-year-old becomes Colin Todd's third acquisition of the summer now that goalkeepers Donovan Ricketts and Russell Howarth have put pen to paper.
Cadamarteri moved to Leeds United last June before Sheffield United snapped him up for £50,000 during the autumn.
The striker became the fifth ex-Bantam to join Neil Warnock's squad, but recently discovered he was surplus to requirements.
It is no secret City have been trying to beef up their attack. According to reports, Todd has cast his eye over at least three other players for that position.
