Thanks for all the help everyone!

I still haven't ordered yet, but here is what I have changed to based on comments:

17 tooth cog is this too cheap?

700c 32 spokes in silver

chainring bolts

I ended up keeping the same chain, going to those Mavic wheels (found for same price as the 27in.!), getting a 17 tooth sprocket (should I have changed the chainring/crank instead?), and picking up some chainring bolts. I'm if those chainring bolts cover the cog bolts pirate was talking about.

thanks again for the help,

Scott
