Bikes: too many of all kinds
Theoretically it can be done, but that doesn't mean you are not risking some serious (or embarassing) problems. In my experience, if you crank down hard and ride hard without a lock ring, you likely will not have any problem.
If you change gears on the ďnon lockedĒ side often, you likely will have problems. Sooner or later you wonít spin it on tight enough and will be shocked to find you donít have brakes when you really need them (i.e. coming off the track into the pits).
If you are not using a lock ring, donít grease the bloody thing! You need the friction to keep the gear on there.
So, yeah it can be done if you put the gear on there tight and donít change it. If you change the gear on that side often Ė use a lockring. Sooner or later youíll have problems if you donít.
