The Trek Super Store was once a Trek owned concept store in San Diego. They have since sold it to another owner. It sells only Treks of course, but it sells a lot of them and the shop does a great job of taking care of its customers. I especially like the concept of their century training program with three speed groups they run every weekend. I haven't been on a ride, but I love the concept.
Not my experience at all. It is by far the worst bike shop in SD. In my visits there the staff has been alternately rude, indifferent and incompetent. I have vowed never to go back there. My last visit was to test ride a new Madone. I got the strong impression that I was inconveniencing the surly sales guy. After asking to try a 56cm performance fit Madone, he sent me off on a 58cm race fit bike. After I discovered the mistake, he didn't apologize, nor was he willing to locate the correct size seat mast for the 56cm I ended up trying. I ultimately decided against the Trek, but if I had liked it I would have been hard pressed to buy from that store. Of course i would have had to go out of town as the two SD Trek Superstores are essentially the only place you can buy a Trek in San Diego.
