While changing cogs tonight, I took a good look at the cog I was taking off, and I noticed that it says "SOMA FABRKATIONS 18T X 1/8" CNC'D CRO-MO"
I never had any real trouble with it while it was on. The cog I put on today had it spelled right--"SOMA FABRICATIONS 17T X 1/8" (etc.)...and interestingly, I bought it from the same local shop where I had gotten the weird one.
Are there counterfeit Soma cogs going around, and did I get one? Or did Soma's provider make a boo-boo on a recent batch, or something?
(Yes, I know I could email Soma or call the shop. But it's ten o'clock at night, and you people know everything.)
