Thanks for the quick replies guys. Soma looks like a good deal but I'm not really sure about the retailer since I've never heard of them and they have nothing on the BBB. So is Soma really that much better than All City or Surly that I should take the risk? I'd honestly be more happy going with Retrogression or Ben's Cycles which is actually local to me.

I have a flip flop so I think I may want to run two different sized cogs. Would it be better to go with a 16 and 18 combo or a 17 and 18 combo? Also, right now I'm really mashing; averaging 65 rpm (maybe 70 on flat terrain) and am looking to try to get up to 80ish rpm so if that makes a difference... I also assume I would have to get a longer chain as well?
