Guess both the BF and Specialized Sirrus must have been correct geometry for me. BF was custom made while Sirrus was off the rack. I had to change the handle bar on the Sirrus, raising it by 18mm by replacing the original with FSA SLK carbon. If there is still a minor fault on the set-up, that would be the bar ends that come with the Sirrus. The grips are soft and comfortable but bar ends are awkward and offer very little in changing positions. And of course both bikes have Brooks B17 Select saddles for maximum comfort.
