Well, I emailed SE about the BCD and they emailed me back and said 104... which made me think WHAAAAT. no way is the SE or the Dawes a 104 BCD for the chainring. especially since its a 5 bolt set up. I tracked down a type ruler here at work with millis and indeed it does look to be 130 after the sheldon brown conversion table.

I think I'll be ordering a 130 Surly 52 tooth chainring. If all goes well I'll post picts.
