What's the difference between my $250 used Nishiki and all the other road bikes I see people using, like Bianchis, Fuji, Treks, etc.
What's the difference between a $500 and a $5000 road bike (other than carbon fiber components)? What's the difference between all the frame angles, fork designs, axles, etc., in relation to ride performance? What do those bikes do that my bike can't? I just can't wrap my brain around the whole thing. I get so overwhelmed when I walk into a bike shop.
I would appreciate it if someone could either direct me to an online resource that will explain everything to me, OR a long drawn out response explaining everything to me - OR!, a phone call, or all three. I have larger philosophical questions about biking, as well.
