Nope. That's a myth. The problem should be fixed for general health, but if a muscle will go through the range of motion needed for an exercise there will be no performance gains from stretching. For some exercises - but this isn't relevant to cycling - performance may decrease as a muscle will no longer store rebound energy to use like a spring.
