I manage a Performance in SoCal. The staff is hit or miss I must admit. Most guys/gals will know a lot about road and mtbs but not track.

I try and stock cogs/lockrings and chainring bolts as well as some inexpensive track wheels at my store but that's just me ordering from QBP or the like and is up to management discretion.

A word to the wise: if you want something and Performance sells it either in store or online we will match the lowest price you can find from an authorized dealer of the exact same item. The smart folk roll in with printouts from biketiresdirect, probikekit, coloradocyclist etc. and pick out all their goodies or order them in store for the lowest prices availible. No, you can't get black ProRace tires if btd had purple ones for $12 or size 45 Sidis if REI has the same ones only in 38 and 52 for $100 but you get the idea. Also, make printouts from Perf's own website. Many times the in store prices are more expensive, so we'll just price match.

Stuff fixed gear riders like myself might like that is readily found in store: Gatorskin tires (and high end race tires), tubes often for $2.97, Sidi shoes and shoes under $50, lots of clipless pedals, $5 bar tape, inexpensive basic clothing, cotton cycling caps, good cheap tools as well as the good stuff, cheap blinky LED lights, lots of helmets under $30.
