You seem to be doing a very good job on your home work, there is going to be some trade off for suspension in weight
verse's comfort. But at the 600.00 dollar price range, none will be in the low 20 pound range, I'm not a speed freak so
weight really does not bother me as much as comfort, and the bike being able to do what I ask of it. Here is my current
favorite ride, I do not even know what it weighed before extra's. Probably around 34 pounds. But it rides awesome and
I love it, makes me want to ride more. Good Luck in your search, Richard
