I frequent the WW site and consider myself a semi-weenie.
I try to find "reasonably affordable" ways to drop weight on my bike.
For instance, using Ritchey WCS Classic bars and Stem and Ti bolts. 335 grams for the combo,
actually much cheaper than a lot of upper end bars that weigh significantly more. I use ultra light tubes and ROX rimstrip. Takes an extra 100 or so grams off per wheel, and costs about 5 bucks. I realize these things don't make a big difference, but to me, it is part of the art of the bicycle (and it feels cool when I pick my bike up). If you are not a weight weenie, that's fine, I don't care. Move on with your life and forget about the weight weenie forum.
