I am looking at the cross check. I weigh about 250 right now. A lot of people say it is heavy. What I am wondering is there a difference in where the weight comes from(rider or bike)? I know when it comes to a car I find it funny to see a fat guy is putting carbon fiber hoods and trunks on their cars to off set the weight of the extra material on their 48inch pants. So if I loose 20 lbs will it be the equivalent as if I purchased a bike that weighed 20lbs less?
