I've found some of the people in camb. bicycle kinda annoying and tuned out. I walked in there one day, and browsed for about 15min, and none of the 3 guys in there really paid much attention to me. It's not like they were busy; I was the only one in there.
I also asked about fixed rear wheels, and the guy kinda hassled me about it, like do you really want one , can you handle it (fixed riding), he then offered to sell me a crap suzue basic hubbed wheel, and sun m13 rim for $100, sans cog,tire,lockring,tape. Uh no thanks, I can get that on ebay for $50, and that wheel is crap.
I then saw a durace wheel hanging above, and asked about that one. He said, that one is for REAL track riders. Ok dude, I'll take my business elsewhere if you really insist.
