Chambers ceased legal action to overturn his Olympic ban and instead aimed to finish his career on a high. He intensively studied the technique of Usain Bolt to improve his own times, seeing Bolt as the new generation's Maurice Greene. Though he was still banned from Euromeetings-organised events, he set a new personal best of 6.52 s in the 60 m at the Birmingham Indoor Grand Prix, then became the UK Indoor Champion, equalling Mike Rodgers' world leading time of 6.51 s. At the 2009 European Indoor Championships he broke Ronald Pognon's European 60 m record with a 6.42 s run in the semi-finals, then won the gold medal with a time of 6.46 s in the final. British head coach van Commenee stated that Chambers had undergone vigorous testing and that his performance sent "a message that you can win and break European records in the proper way."
