So now comes the fun part...upgrading the wrecked parts on my bike!!! Woo hoo!! I've already decided to switch to the Shimano 105 7500 groupset; now I need a new set of wheels--any recommendations in the $350 range? My frame is a (size small) Giant Avail (turquoise and white). For reference, I ride around 100-130 miles/week and I'm a small to medium-sized rider.
