Rocket Rings
I've seen several posts recently about these Chainrings. They look like a saw blade but they are cheap as hell. What is the overall consensus on these chainrings. My bike came stock with a Truvativ Touro crankset and chainring and the chainring on it is horrible. It is so far out of true its unreal. I can look down at it while riding and watch the chainring pretty much wobble. But I saw on Amazon.com the rocket rings are like $13 and that can't be too bad of a deal to at least try. So if any of you all have them, do you like it? I may go ahead and get one till I can save up some more for a nice crankset and chainring.

I have a 43t that i got for something like 8 bucks shipped. I tossed it on and with about 5 mins of messing around with it got it to spin pretty round. Can't beat the price, though I do hate the extra set of holes. I think I'm going to mill it down some once my semester ends.

I've got about 2k miles on two different ones, I like the high teeth but I find they aren't made of a hard enough alloy, they deform at the base of the teeth. I say pop for the $25-30 Sugino or Salsa rigs, they're much higher quality and wear better as well.
edit: if your current ring wobbles, grab a big adjustable wrench and straighten that bad boy out. It's not that hard to do, and it doesn't have to be perfect.

As posted before the teeth on my ring deformed pretty quick but that could be because it is a conversion with a chainline that may not be perfect. If I were to do it again I would most likely get a slightly better quality one that would last longer.

I have a 45T 1/8" rocket ring on my beater rain bike and I have no real problems with it. Its gone 2000+ miles in **** weather and is still going strong. It seems to work just as well as the $90 Sugino Zen chainring on my other bike.

Bikes: a bunch.
I had a rocket ring that I ordered from Sheldon that was machined improperly. Some teeth were nearly half the thickness of others. I should have returned it right away, but instead ran it and the narrow teeth wore really fast.

the only two things i've ever heard bad about them are the above post and someone saying he thought they were total ****, though there was never any reason given.

still cant find my top tube pad.
yeah those are 170mm bullet proof cranks, the ring is on the inner spider, and it is so tight i couldnt run a larger ring if i wanted to.
it took me a bit to sort out creaking chainring bolts, but i dont mind the combo at all. it isnt as pretty as some of those out there, but i cant see then when i am on the bike anyway.
the bike has a italian bb shell, so it is an odd size, but i cant remember which bb is in there right now. it was cheap as hell, and on my next bike i intend to go with a nicer one, but since this one was built on a budget.

Man, I was just searching velospace and some black bulletproof cranks w/ a black rocket ring looks pretty slick. I think instead of dropping $200 on high end cranks, I may just go ahead and get some bulletproof cranks. Are your bulletproofs pretty stiff and strong?

strong yes. stiff eh. some people have mixed feelings on them, they are stiff enough for me and i have used them a 900 pound bike with no issues.
I skid and slid and do all sorts of dumb stuff on mine with no qualms at all.
