I recently purchased a Campagnolo Nucleon clincher front wheel on ebay, very good condition, spokes tensioned and trued. I have been very happy with its performance on the flats, but this weekend I did some mountains, and on some of the descents where I reached above 40 mph, I detected some noticeable flex that a little unnerving in the corners while trying to hold a line. My previous front wheel was a 32 spoke mavic open pro with a Campagnolo Chorus hubset, and it would track true through turns no matter what the speed. Now I do not believe myself to be that heavy of a rider a 160 pounds, and I am wondering if this is just the trade of for a lighter wheel. Has any one else had this experience. Any input would be greatly appreciated.
