We buy clothes and most parts on line, but bikes at the lbs. I mean, I got a NEW FRAME after two years, because i just was not happy with what he sold me in 2006. Sure, I paid for the labor to switch over the components and I paid for a new bar and short reach shifters. But the new frame cost at least 3K.
I am not always happy with this shop, but I am up front about my needs and they work with me.
