Next season I'm looking at getting a pair of Carbon aero wheels to add to the group. Ones that I'm looking at are Bontrager Carbon, American Classic carbons 38", Zipp 303, Reynolds. Right now I'm at 180 pounds and ride pretty smoothly. I've lost 25 pounds and plan on dropping about 20 more by next spring(time of wheel purchase). Any opinions from people who have used any of these wheels is appreciated.
