Portland, Ore., bike rental

Hoping someone on the West Coast can help me out with this one. I'm going to see a friend in late July/early August in Portland, Ore., and we're going to do a triathlon together! Can't wait.

But I don't want the hassle of flying across the country with my bike for a short-distance race. Would rather just rent a bike -- preferably a tri bike (for fun) but I'd settle for a road bike.

Does anyone know of a shop that'd rent a GOOD bike to me for a week? I prefer something with mostly Ultegra components. I'm not picky on brand and not worried about the cost.

I don't know of any rental places per se, but I'm sure that one of these two excellent bike stores should be able to point you in a helpful direction if you give them a call:
