The main LBS here seems to try to cover most of the market -- you can buy an Electra cruiser from them, or a $4-5K Trek roadie. Kids' bikes, MTB's, BMX -- pretty much everything but triathlon, which another shop in town specializes in. I don't go there too much anymore, since it's not as much fun to me to look, fondle and drool over parts. I've bought saddles from them, energy products, they handled a manufacturer's part purchase for me once, so they do their job -- I just do my own work. (When you spend 13+ years trying to make big-box crap useable, you learn tricks & how things SHOULD work....)

I wouldn't hesitate to walk in there if I felt they could fill a need I had.
