Is there such a thing as a bicycle with spinning axles? Not sure what good it will do you; If you tighten both end-nuts on a standard bicycle axle hub, then the threaded axle and the wheel hub become “fixed” so that both the threaded axle and wheel hub spin together; instead of them free spinning on the ball bearings in-between them. I am not aware of any bicycle wheels with fixed axles; because then you need to provide a way for mounting the free spinning axle to your bicycle frame (which adds weight). You can convert the axle threads into a smooth surface by either: – screwing a smooth metal rod with interior threads over them (you need another locking nut at the end of the rod so it does not spin loose), or – filing exposed threads down flat ——————————————————————————————– Power required to overcome aerodynamic drag is proportional to the CUBE of the velocity (or SPEED), and it is proportional to the CROSS-SECTIONAL AREA o
