Thats what I use for fast commuting. Seatpost rack gives me lots of space with a QR. Entry level bike gives me a liwer value so I don't stress about parking it while I'm working. Its running 53-39 11-34 8 speed so the shifting has some largish gaps but I hate pacelines anyway. Rather ride alone than chase another wheel. Strip off the rack ane its plenty fast. No fenders but I carry a change of clothes so I care not if I get wet. Got a rain bike if its pours down.
