Oleanshoebox, ( I bet there's a story behind that name)
Cyclery USA has some plusses and minuses.
Plusses: They're the closest. Their head mechanic is very good. I get 10% off non-sale items for being a member of the Riverside bike Club.
Minuses: I've had the same issues with service. Once I had to barge in on a conversation between two employees to get them to notice me. Since I've been there a few times they recognize me and the sirvice is a little better.
I really can't recommend Circle City Cyclery in Corona. They have a limited selection of Trek and Specialized road bikes. They aren't too keen on discounting from the list price.
Don's bike shop in Rialto was better. I wanted to try a couple of Cannondales and they were the closest. The owner was very helpful and rode with me around the block when I tested out four different bikes. They didn't have a huge selection of road bikes in my size, though. To be fair, I was there before the 07 models arrived, so I was testing out the 06's that they still had in stock.
If you want to go to Pomona, check out Coate's Cyclery. I went there a few weeks ago because I wanted to test ride a Lemond. They were great. Cory, the owner (I think) greeted me at the door and asked what he could do for me. Let me test ride a lot of bikes and answered all my questions. I ended up buying a Bianchi Vigorelli from them.
