ok, i gotta start with a disclaimer, which is: i don't support local shops much, and i don't have a lot of love for shop owners/drones in general. But, looking at this thread, it seems that alot of you have unrealistic expectations.
1-Used Bikes. I love em, but any shop that sells them is going to be accused of selling stolen goods. Some ARE selling stolen goods,others aren't . but any shop selling used bikes needs to decide whether the hassle of dealing with that rep is worth it. I, for one, can't fault a shop for only stocking new stuff.
2-Stuff in Stock. It's tough to know what to stock in a shop. Sitting on a bunch of inventory is no fun if no one is ever going to buy it. Now, this isn't meant as an insult to the citizens of RRB; i hold y'all in high regard for this very reason, but y'all have some
very bizarre needs as far as bike parts go. I've worked in a shop, and in the new millennium, you almost never get customers looking for 21.1mm stems and 20" white walls, and when you do, they want to spend minimal amounts of $$$. True, it's a sad thing when mechanics don't know that there are 21.1 and 22.0 and 22.2 flavors of 1" quill stems out there, but when i emailed the ppl at profileracing about their wedge stem, the guy told me "1" is 1", end of story". He was cool once I set him straight, but it still told me alot about modern typical bike ppl. For the record, the wedge stem is 21.1mm, and to the profile guy's credit, the 21.1mm will fit in any 1" steerer tube (although I'd use a shim in a 22.2mm steerer tube if i were to go that route.) Point is, you can't expect the small local bike shop to have any sort of massive inventory, especially in oddball parts and outdated sizes. (be nice if they did have it, though.)
3-"What is this going on?" Yes, this is a very arrogant-sounding question, but the guy needs to cover his butt. When ppl ask for a part in a bike shop, and the employee just sells it to them without question, there is a pretty good chance (33%?) that the customer will come in the following weekend, trying to make a return, and p'ed off that no one told him it "wouldn't work" for his application. Worse,the component in question is likely to be damaged by hamfisted attempts to make it work, and things turn ugly. So, the wise lbs employee will ask, to make sure that ugly scene can be avoided. Deal with the same shop enough, and they'll eventually learn that you're one of the guys they don't have to ask.
The fact is, if you're on this site, you probably shouldn't be going to the bike shop much. You already know what the part is going on, what part you should be buying, and even if you're buying the "wrong" part, you know the right way to "make it work". Bike shops are for ppl who don't know what they need, or don't know how to install parts or fix bikes. Or, for rich ppl who don't want to get their hands dirty by wrenching on a bike, so they have the shop do it for them. (Hence, the tendency for shops to cater to high-end roadies and mtb guys.) None of us are one of those guys. You KNOW what you need, you KNOW the shop won't have it, you KNOW you can order it yourself for way less online, and you KNOW how to install it yourself. And, frankly, you know you WANT to install it yourself. The LBS is an essential thing for neophyte and/or pampered cyclists, but it is an unnecessary middle-man for the RRB/DIY/crusty&greasy types who post on here...
I've been hitting the local bike co-op lately for weird shhh i don't have on hand. I bring parts i don't need anymore or stuff i've trash-picked in as donations, and in return, i can count on them should i ever need a 21.1mm stem or an s-6 rim...free of charge.
Sorry to write a book, but i do feel some sympathy for the scheisters running bike shops, and the clowns who work there. I don't shop at Victoria's Secret for underwear; they don't have what I need in-stock.
But i'm not mad at Victoria's Secret about it, and i think that's a pretty good analogy for my attitude towards the LBS.
