New Bars, New Stem, New levers.. so why does my bike feel faster?

hippy I'd be thinking of outside factors before putting it down to bar and stem change. Time off bike? Good day? Good mood? Shag last night? Tail wind? Higher pressure in tyres? Psychological aspect of having NEW kit?
I notice position differences when I change stuff but not a performance difference. It's always the legs that dictate performance.. new kit + stuffed body = shit ride. For me. ymmv

yeah, but they feel wider, and higher. i did add the 5mm spacer, that could be it. but, it feels cleaner, tighter -and i wasn't even expecting any change, so i don't put it down to my imagination. I am very highly atuned to these things though...
