I've read the article as well and that Peter Weigle bike is very light, is probably very durable, and would be incredibly expensive. I wouldn't be surprised if you wouldn't wait a year or two to get one. I am sure you could get some carbon framed bike in that weight for far less, but a bike like the Weigle is in a very different class, kind of a work of art. Having said all that I ride for exercise, trying for 20 miles a day, most every day, and 5 pounds more is not a problem for me. I will concede I don't feel that way about studded snow tires, which while good on ice and snow, are not a lot of fun to ride on due tontheir sidewall rigidity and overall heaviness. There's a lot of sprightliness lost with those tires.
