Dmitry: The only reason you're beating a dead horse is that it's frozen in
place up there in the cold north and you don't know it's dead yet.
The original Q was on a straight thread hub could a lockring be put on and
could one use a fixed cog on such a hub.
No one wanted to put a lockring on the same thread size as the cog on a
track hub.
A track hub by definition is one thread size for cog, and a smaller thread
diameter in LH for the lockring.
Whether it's single or double sided is not important.
Some hubs were made with both straight thread for freewheel or cluster and
the other side for a fixed.
Many people want to put a fixed cog on their straight sided threaded hub and
if it's tightened tight enuf it will usually stay tite and not roll off, but
I wouldn't take that chance, and never ride it on the track.
Using brakes on a fixed road use is smart in today's traffic.
We used to ride fixed in traffic years ago and had no brakes, but traffic
was much less and we knew how to glove our wheel and stop very qiuckly with
a little back pedaling.
Many times there is enuff thread left on a straight hub if the cog thread
section isn't too wide to sneak a BB lockring on. and save the expense of a
new wheel. Not really to race but fixed gear training and riding around is
fine.
Lots of guys used to strip down their road bikes and put the fixed on that
way and then several months later convert back.
