I've weighed my bikes just using the bathroom scale method. I weighed both bikes with their saddlebags attached too. I always thought my new 2015 Scalpel 29 Carbon 3 weighed about the same as my 2000 SuperV700SX. When I've been at trail head and getting to talk about bikes and people lift my Scalpel to check the weight and see how light it is. I tell them its about 30lbs. Then I check out their alum. framed bikes and they certainly feel heavier, even the hardtails. So yesterday I was curious about my SuperV. So I weighed it and to my surprise it was about 0.6 lbs LIGHTER than my Scalel 29.
