Question Changed. See Below for Original.

My local bike shop neither carries fixed-gear/single-speed parts nor is very knowledgable about the topic.

Should I find an online storefront to take its place? Or try to work with my LBS to get the parts I need?

Original Question: Online Shop Suggestions for Fixies/Single-Speeds

I'm looking for a reliable online shop for fixed-gear/single-speed parts. I have a frame and fork and am wanting to buy new, quality parts to complete my first build. Any suggestions?

Looking for (EDIT):

• Fixed/Free wheel-set, cogs and crank.
• Shop specializing in, but not limited to, fixed-gear/single-speed parts.
• Quality customer service by email or phone.
• A local bike shop with a good online storefront.
• Prompt shipping.
• Ships to U.S. (Texas)

I've tried my local bike shop for these parts, but unfortunately they were not very helpful after mentioning single-speed (they were cool about it, just uninformed).
