Not a lot, but thanks for the heads up. I might just go down to the Bike Dump again and see if they have any clincher rims in decent shape. EDIT: I also just found an eBay seller who has a pair of Sun M14A rims for $45. Could be promising...

Went there today to see if they had a 19t cog or smaller chainring and went away empty handed. They measured the BCD of the Sugino cranks and told me it was 150mm and I would have a hell of a time trying to find a chainring that would fit, but I used a measuring tape at home afterwards and it looks like 144mm to me. The techs also agreed that I made off like a bandit with this deal.

Phat Moose said they wouldn't be receiving their Surly order until next week, so I'm stuck pushing 51x16 for a little while longer.
