I'm currently at 260 and falling...I have been trolling craigslist and found what i feel is a good deal on a 2005 Cannondale R700 road bike. I am concerned about the wheelset (WH-R550) and how well it will handle my large weight. I already have a cross bike I beat up for commuting and utility riding, so i don't intend on carrying any extra loads (besides myself) on the bike. This would just be a bike for riding fast and HOPEFULLY dabbling in a few triathlons with next year. Does anyone have any feedback on how well this wheelset will hold up to my particular flavor of abuse? What i've read online seems to be a bit dated and everyone seems to have vastly different opinions on the quality.

Thanks for any insight you can provide..
