Creaking

I've been riding the new Rob Roy around for 100 miles now and over the past few rides I've been noticing some creaking coming from the crank/bottom bracket area. I took it into the shop and had the guy who built it up for me take a quick gander. It turns out that the spiffy blue chainring bolts I used are trash. One sheared into two when he was taking it off. I'm now using steel bolts thanks to him pulling some out of his personal stash since the shop didn't have any single ring bolts on hand.

Here are a couple of pics of the bike right after it was built up. Not much has changed other than the addition of a cyclocomputer and the swap for mundane looking bolts.
