I used my Cosmic Carbones for the first half of this season exclusively. I just love 'em. Changed 'em out for the last ride I did that had a lot of climbing and I used a lighter wheelset. I'm looking at some Boyd tubular 32mm wheels. They are about 1200gm for the set and although I wouldn't use them as an everyday wheel, I'll probably use 'em for a week or two at a time and alternate. They should lost a good long time (i.e. years....)
