I learned to beware of the LBS as soon as I started spending serious $ on bikes, the hard way. I wanted my first roadie to be a touring bike, but at that point I was too green to know exactly how a touring bike and your average racing oriented roadie differed. So I explain to the main salesperson at my local LBS what I want, and what my price range is. So he steers me towards the compact frame roadies, and I ask him about tire clearance;
"Oh, people who do long tours never use anything bigger than 700x25(!)" he says.
Like I said, this was my first non-MTB, so I had no idea this was horsecrap.
"Can you mount a rack and fenders on it?"
"Sure, no problem!"
So I end up buying an alumininum, compact frame roadie with no clearance or eyelets for fenders/tires. A nice bike, but not a tourer. I went back in for fenders, the guy sells me the fenders, while he's looking right at my bike, and he swears they'll work. I get 'em home, they don't have enough clearance. The bolt on the seatpost broke, about a month after I got it, while it was still under warranty, this same guy tries to charge me for it.Anyway, this turned into a very expensive mistake, and if he would have just tried to help me with the initial purchase of the bike instead of trying to get rid of what he had a lot of,(they got new models in a couple weeks later,) I would've spent less and been much happier.
Suffice it to say, I rarely go into this LBS anymore, and if I do, I don't deal with that sack of **** anymore. Sorry, it just felt good to tell that story!
