Cavern Cycles
Track/Fixie specialists and any other kind of ride too. Not a huge store so not a lot of stock but what they do stock is good and they can get it for you too. One nice feature is that they have a lot of fixed/track riders as friends and customers so there are usually a few used frames/bikes and always plenty of new parts to keep you rolling. And new bikes of course. Friendly people too.
