As a hiker, the first thing I look at in a peice of gear is the weight. Absolutely essential to hiking. If the seller doesn't list the weight, up front and center on its webpage, the gear will not sell. The seller will also be considered stupid.
But so far, none of the bike sellers list bike weights. Why? My thought is that everyone probably understands the general weight of bikes made of carbon fiber, aluminum, steel, and so forth, and the difference is considered neglibible since you don't feel every ounce (unlike in the hiking world). Right?
Regardless, what does your bike weigh? I've asked the weights of some carbon fiber bikes in the local shops and gotten 15 pounds. One guy there said his weighed 14 -- and he was very proud of his bike. What about yours?
