Here's an idea from a forum lurker (for years)...I use a set of Mavic Heliums (clincher and tubular). They weigh 1500 to 1600 grams , and I have new bearings pressed in every 20,000 miles. Some of these older wheelsets are avialble on ebay at very reasonable prices, are very light and totally reliable. My first set of Heliums came on my S-Works M4 Road, same wheelset Festina used on their team bike in 1999 to 2003 (or 4?).
Anyway, if you shop carefully you really don't give up much to the new expensive carbon wheelsets. BTW I'm 220 (100KG) and 6' 3.5", I've rebuilt my Heliums twice now on both clincher and tubular.
So do some reading around wheelsets used on the Tour back in 2002 to 2007, then go looking for them, you only need to mke sure theyre supported and can accept press-in bearings. Personally I like Mavic, but thats my bias.
