Dasaolu catapulted himself into 100 metres medal contention at next month's World Championships in Moscow with a blistering 9.91 seconds in the semi-finals at the Alexander Stadium.
The 25-year-old became the second fastest Briton of all time, going quicker than even Usain Bolt has managed this year, but opted to pull out of the final after experiencing cramp.
In his absence, 35-year-old Chambers took the title and sealed his place at the World Championships with a winning time of 10.04secs - a season's best.
Dasaolu is also certain to be on the plane after a run which ranks him fourth in the world this year.
Only Tyson Gay, who tops the rankings with 9.75secs, Asafa Powell, who did not qualify for the Jamaican team for Moscow, and Justin Gatlin have gone quicker.
Bolt, the double Olympic champion and world record holder, has a best of 9.94secs this year.
Dasaolu's time, which shattered his previous best of 10.03, was a stadium record. Former Olympic champion Linford Christie is the only Briton to have ever gone faster, with his mark of 9.87 set 20 years ago.
