For context, this guy set a world record in the 4k Pursuit, and did it without shaving off that 'stache:
The same series of Specialized videos that proved there was an aero benefit to shaved legs also proved that there's no aero benefit to shaved facial hair.
Also Ashton and literally every track cyclist shave their legs.
To the OP -- do it or don't do it because you want to. Aero benefits are probably trivial at the amateur level but if you want to do it because it looks and feels good that's perfectly valid, despite what some easily triggered insecure people on this thread seem to believe.
