Lockrings, do you?
 
Do you guys use lockrings at the track? I was recently heckled into not using one, and it makes sense why one isn't used. It seems that nobody uses them and I was late to the party so I figured I'd ask for fun.

Nope.

It doesn't make you go faster, so no. I've seen two cogs pulled off *forward* in standing starts (tearing the threads off the hub). In ~20 years I've seen one spin off backward and it happened from the rail to someone who had just put the cog on and apparently didn't tighten it at all. He probably would have screwed up installing the lockring, too..

I carry them in a variety of sizes because some tracks allegedly require them, but I've never used them.

Coming from a street fixed gear rider, I was so paranoid about using a lock ring. The guys pointed out that it's silly and not needed, I won't be doing any sweet fixay whip skids on the track ever so I shouldn't spin a cog off. My gear changes seem to be a million times faster now :P

When I'm on the track, I don't. When I am training on the road with a fixed gear with a cog over 15 teeth, I use a lockring. I figure that, on the track, if I manage to get into a situation where my cog comes loose, I have bigger problems than my cog coming loose. Larger cogs have more of a chance of breaking free under back pressure. Of the people I know who use a lockring, they really only tighten the lockring a little more than hand tight.

I use them. Once during a match sprint, when not using a lockring, my opponent suddenly slowed down in an attempt to get me to pass under him. When I jammed the cranks backwards to slow down, the cog spun loose. No harm done. We were moving slowly. I just rolled off of the track.

So, yeah, I use them.

I use 'em. See no reason not to

I use a lockring, because I use Miche splined cogs & carrier.

I've had a cog come lose from slowing down quickly. And i'd already done some standing starts on the gear, so it wasn't a tightening issue.
so... i use a lockring.

I've had a think about this after seeing the FGF thread. I've always used one because I'm really only a beginner, despite coming into my fourth season now. As I've moved up the grades in racing, I've encountered many circumstances that have required serious backpedaling to slow down quickly. Also we don't have a really good structured training at our track, so there's also a lot of circumstances there that have meant washing off speed quickly. I'm not a gear hound. I haven't changed my sprocket in over a year. I have found that changing the chainring has been fine for me, and I have handled the ~2GI jumps in gear ok. I also raced indoor on the boards over our winter that has just finished, and have been finding my legs so to speak in respect of gear choices with a bit of broader experimentation.

Now that I have moved up the ranks, after thinking about it, I could easily survive without a lockring in most racing. In the higher/better grades there is far less of the silliness that comes with the more inexperienced grades. The racing is much better. I will still use one for the reasons at training as described above, and because thus far in my racing life, an extra minute or 2 concerning myself with a lockring is of no hassle to me.

This (match sprinting) is the only time I use them, for this exact reason. All other times I DON'T use lockrings.

I have always been told by coaches that it is actually safer to not have a lockring... appaently if you crash and your feet don't release, you can badly damage your knees with a lockring in place... without a lockring the cog can release and spin, therefore absorbing some of the tension. (I have not seen any instances to back this up, it's just what I have been told by people who have ridden track far longer that I). :)

No reason not to. The only exception I can see is if you both lock and strap your feet into the pedals where they cannot come out. Pedals will release.

Cogs occasionally may release if you break hard when they are first installed. But a couple of jumps on the track and the cog is not going anywhere. Unless of course you skid stop. That will break loose a firmly torqued cog.

Lock rings are not strictly necessary on the track if you ensure you torque the cog on good, and are sensible with braking. Still, I use one - it just makes sense.

I use one. I was in a hurry once and didn't put it on. Didn't do a hard jump or anything to tighten, and spun it off when trying to slow down during the race. I coasted off, but we were doing 25+, so it took me a while to slow down. I'd rather not repeat that. I don't see a reason not to use one.

Is British Cycling the only organisation that requires riders to use a lockring?
I have to (under ruling, which I won't find/quote as nobody here rides under BC).
Although, I'd probably use one anyway...

You didn't tighten your cog properly when you were hurrying then...

FWIW, the old Specialized Trispokes had a design that didn't even allow for a meaningful lockring. Front and rear hubs were identical (and the same hubs as for road- just an axle swap), and to use one as a rear you screwed an adapter onto it, then the cog onto the adapter. In principle you could use an adapter that would allow for a lockring, but then you'd just spin the adapter off in the unlikely event of putting that much back pressure on. The adapter I had was kind of goofy - it didn't even have flats to use a wrench on, so I ended up using a pipe wrench on it (and carrying the pipe wrench to use as backing wrench when removing cogs).
