Cog and Lockring Cost vs Quality?
This might be a dumb question, but does it matter what kind of Cog and Lockring I get besides the number of teeth? Just checking out ebay and seeing differences in prices betweenn 1/8th 14t cogs, quality and resistance to stripping maybe?
Thanks.
Thanks.

Material matters too and some cogs are stamped.
Shimano/Dura Ace lock ring is probably the best bang for the buck.
As for cogs, I've only used two of them and I don't have anything to complain about either of them.
Price and quality does not necessary correlate, but EAI cogs are good cogs to use. Of course they can cost up to 30 dollars or so.
Stripping only occurs when you really messed up at installation, grease the threads of the hub and torque it down with a good chainwhip, grease the threads of the hub for the lockring as well and torque it down with a lockring wrench.

Get a Dura Ace lockring the first time around. Ive gone through other lockrings in seconds trying to unthread them with a lockring spanner only to have the notches on the ring scrape right off.
As for cogs, there's already been much discussion on here about different cog quality. I would suggest going for at least a Surly or Dura Ace cog. I have a Dura Ace and just changed to an EAI for tooth count.
Best advice: Dont go for those ebay bargain cogs and lockrings. Chances are you'll end up spending a lot more after they get damaged and you have to buy another one. Do it right the first time.

A shimano dura ace lockring are a must; the price for one isn't half bad either.
I would go with a Soma cog if you're looking to be somewhere in the middle between cost and quality/ durability. Otherwise it would be EAI which are a tad bit more expensive but also durable as hell.... I heard surly cogs are also durable but the price is close to that of EAI's....

I usually use DA lockrings, but sometimes I need thicker lockrings such as Surly one. ... Do you guys get problems with DA lockrings not getting enough threads? (ie, Go on too far)

I do believe in theory anyway that the more expensive cogs are more true so your chain tension is more consistent and pedal stroke more even. A good lock ring just makes sense - safety issue and pain in the butt factor.

Cog runout shouldn't be as much of an issue as it is on chainrings.

I have a soma cog/lockring. Seems to be of good quality.
Thinking I might spring for another soma cog (16t) so I can change my chainring from the 52t one I Have on there now to something more reasonable like a 46 (Which gives me the same Gear Inches +/- a few tenths).
I feel like the Huge chainring looks silly on my bike.

cg1985,
No way. Huge chainrings look trick! Well, as long as you don't also have a huge cog. Boy, I had to pay attention to my spelling on that one.

Well I have 52/18. So it's not a "huge" cog, but not small either. the tip of the teeth is about even with the flange of the hub.

I have stripped a hub once from using a cheap lockring. It only engaged 2 1/2 threads out of the 5 on the hub, due to the cog hanging over the remaining threads. Bought the same formula hub new and a surly lockring with its lip to engage all of the threads. Its been working under far more harsh riding conditions then stripped the hub. I'm using the same cog as before, its steel, just not sure who makes it.
I did my first ever hill climb and decent, brakeless, SPD clipless with a helmet. That was fun and scary on the first lap, then I didnt want to stop, its the best ride I have ever been on. Beats the heck out of roller coasters.
The paulcomp ring are expensive, but I could see you might need them if your cog was thinner then the one on my bike.
I don't think $14-$20 is that expensive for a great quality lockring, I paid $17 for it at a LBS.
Yes, the first lock ring I used was installed correctly.

once I figured out what I wanted/needed in the way of a cog I bought a Bens Cycle cog and lockring both are awesome and what really nice is I can easily check my lock ring tightness with the wheel still on the bike

Bottom line: NEVER skimp on a cog/lockring set with aluminum hubs.
