i got mine from peak cycles in golden (bikeparts.com).
if you place the order online and choose "will call", i could be persuaded to pick it up for you tomorrow before heading to boulder. (if that helps). though i think the cutoff time for next day might be in about 5 minutes...
or you could drive to golden.
