I'm sure this is brought up often enough (reply with a link to a thread if that's more appropriate or something). Does anyone have any information on the merits of choosing one size over the other? Are 3/32 less noisy and wear your chainring/cog less while the chain itself is less robust? I think that's what I heard but I could be way off. I am using 1/8" right now on my first fixed gear and after about two months of daily riding is holding up nicely and I like it, I'm just wondering what the difference might be.
