In Vegas there are very few full service bike shops left. This is the best I've found. I built a mountain bike from good used parts bought on ebay and other places and once it was running they fine tuned it for $50.
They told me I built a $900. I only spent $250, including the tune-up. Runs like champ, I've bought a few other things there since, no high pressure sales, no up-sales, no bull.
LOVE IT!
