another cog thread.

getting a new chain and new cog. switching my other bike to 1/8th inch. probably sticking with sram pc-7x. has served me well in the past, seemed to hold up nicely.

i've been using a surly 17t cog and it's just fine. i'm looking for a reason to try something new. i'm interested in Milwaukee bicycle co, eai deluxe, all city stainless steel, soma, eighth inch. there are probably more in this price range.

anyone have any good/bad experiences with any of these cogs? just looking for durability, roundness, and something super quiet. any advantage of having a polished cog besides looks? should i be thinking about chainline?

I've only really used soma, and it. is. silent. My retrogression cog was nice too.

I love my EAI cog, EighthInch was good too. How many miles have you got on your current drivetrain?

You can't go wrong with a run of the mill (non - plated) EAI or Soma. I can vouch for both.

EAI and Soma are winners in my book. Both run pretty quiet with KMC-710SL's, with the EAI a bit better in my opinion. My next cog would likely be EAI again.

You're looking for a reason to try something new? There is no reason.

Is your current cog the wrong gear? Is it worn? If the answer to both is no, then don't waste your money.

loudness is also a valid point. A friend of mine had a dura ace cog that was very loud like a buzzsaw he changed to a EAI and it was quiet as a cat

Hated my Dura Ace cog. Love my All City cogs.

I never want to use anything other than EAI cogs.

Lets beat this horse with more EAI cogs.

my kilo has been stock for years and i've been running that original 48x16. the skid patch thing bothers me so i never skid on my kilo. i run 49x17 on my vigorelli. so i'm looking for a new gear for the kilo. probably putting the new stuff on the vigorelli.

i've always wanted to try eai, the shops around me never carry them. i love buying small parts at the lbs.

i ride to and from work 6 days a week for 2 years now with some days off for vacation and rain days on my rain bike. about 10 miles a day. plus riding for getting around doing other things. so maybe about 6000 miles.

i like to take the chain off and clean every 2-3 months. always keep in at least wiped down.

Tell your lbs to call EAI and set up an account.

I have a 1/8" soma 22t that I abuse via winter riding. Almost no wear after 2+ years.

I am very much glad that my siamese cat doesn't look/sound that ****ing ugly.

cat from hell!

I'm not a fan of Soma cogs. The 2 Soma cogs that I've used have signs of wear on the sides of some teeth, leading me to believe they aren't laterally true.

I wish SRAM made cogs.

Just pretend they do and keep buying better ones.

No moving parts to jam or break, and they could copy an existing design. It sounds like something SRAM could handle.

Anyone know where I can get a eai cog in NYC. I see chari and co has them but they're charging 40.

pretty easy to verify.

Of course they are.
