The highest recorded weight that I have is from Jan. 1 2005. I was 318. right now I have gotten down to 242.
I ride a 2009 Jamis Aurora, it is the bike in my sig. I have actually had no trouble with the wheels so far, but I only have about 400 miles on it, so hard to tell. The first bike I wad was a Diamondback Insight 1, and no trouble with it either.
Both of these are 32-spoke wheels, and I had them checked before I took the bikes because I know of the issues with weight and factory wheels.
