As long as the lockring has two opposing notches (most do, including
the Dura-Ace one you list), Park's SPA-3 does a good job:

My favorite is a pair of Channel Lock pliers, with a bit of the jaw
ground away to make a "tooth" at the end of each jaw to engage the
notches in the lockring. Works great for all sizes of lockrings,
many sealed BBs, etc., and also works well as a Channel Lock pliers
for other purposes.

I'll see what I can do- it was dead easy, took about 10 minutes with
a Dremel. Inspired by the VAR pliers-type lockring tool.

Drop me an e-mail to remind me in case I forget. I'll post it to a
Web site and post the URL. Now, where's the digital camera gotten
to?

http://sheldonbrown.com/harris/tools.html#lockring

Certainly off-topic, but looking at the Hozan hook reminds me: I have
an old, old, (older than most readers of this newsgroup, I'll bet)
10-speed which I still ride as a "around town" bike, and it has a
round headset "nut" with 4 notches in it. It looks like it takes a
small version of the Hozan hook (which I have, and it doesn't work)
but I've never found the right tool. This "nut" sits above the
adjustable cup and below the brake hanger.

Anybody know if such a tool exits? I guess it must of, at one time.

TIA.

That is am interesting system, used on Japanese sport bikes
in the seventies. The small three-notch lockring holds the
bearing adjustment ( use the other end of the Hosan 205) The
large locknut only holds the brake hanger.

Tom said the Hozan didn't work for his, but my understanding is that's
what the small end is for. I never found anything else it fit, anyway.

However, sometimes it's necessary to take the Hozan tool to a grinding
wheel, both in thickness and sometimes in the longitudinal dimension of
the barb.

Indeed I did read too quickly and I think Sheldon's right.
The nicely forged Hozan needs a little finish work to fit
properly. On both ends.

And I never saw one with _four_ notches either, always
three. Hmm.

/s

I guess I am coming in late on this one..

Ok what I use is...

I'm not too keen on modifying tools.. but I guess the industry rarely asks
the frontline people about products.

I use a weird older park bb lockring wrench which has a pivot so it kind of
wraps around the lockring..

On Miche hubs the lockring is pretty spiff since theres a Elite lockring
tool that fits perfectly into the notches and I believe there is 3 or 4 of
them..

I would make alot of sense for the hub makers to start providing a lockring
tool.. I am still baffled by the sovos how did they think were susposed to
lock it down?

And for that matter Sheldon if you are reading this any tips on preventing
the sovos hubs from stripping out under torque?
The only hubs (with the exception of Phil) I have found so far to not strip
out under load (ie braking force) are the Miche.. I used mine for a brake
for quite a while Dura ace and Campy I had people strip out.

Well, I see I messed up on a couple of things with my original post.
Yes, there's 3 notches, not 4; I was going on (bad) memory there.
Also, since the picture of the Hozan hook at Harris Cyclery only shows
one end of the tool I said "I have one" but what I really have is the
Sugino bottom bracket tool that has the hook on one end and a large
"box end" style tool on the other end.

In fact, scrolling down just a bit on the Harris Cyclery page I see
the Park HCW-5 tool that looks to have exactly the correct 3-hook end
on it that I need, though I'd guess you'd have to remove the top
locknut and brake hanger to use it.

Nope. That tool fits the same radius on both ends, and is too large for
the headset application. The three-notch end fits _some_ old-style
bottom bracket lockrings and is less liable to cause cosmetic damage to
the lockring.

I don't particularly recommend the HCW-5, mainly because it's thinner
than the Hozan, so it's more painful for those of us with delicate hands
to use.

Use only high quality sprockets. I generally recommend Dura-Ace or E.A.I.

There are a lot of cheapo sprockets out there which tend to have very
much less thread engagement.

I also advise against using the hub for major "braking." That's what
the brake is for, and extreme resisting is harmful to your leg muscles
as well.

Yes I agree with you Sheldon the rear hub shouldnt be used for braking but..
alot of people do. I dont use the DA or EAI? not even sure where to get the
EAI from.. I usually carry the Miche cogs.. what do you think about the
quality of them versus the others or are they compareable..?
Btw remember when I sold you (harris cyclery) a bunch of frames I've been
very curious how you guys made out with them.. any of them break?

Benjamin Weiner asked:

Quoted message said:

Do you mean fewer threads, or less engagement due to
threading being further from spec?

I looked at some track cogs and most of them had about
6-7mm of thread - several name brands and two without
marking. One had only 4.5-5mm of thread, this was an
unbranded one which is possibly stamped - it has a sort
of rounded inner diameter on the outer side before the
threading begins.

Mainly the former. Out of spec could go either direction.

See the chart at:

which lists measurements of every brand of fixed sprocket I could find.
