OK, PEOPLE -- LET'S GET OFF THIS POGO-STICK CRAP! Yes, front suspension will add weight to the bike, and if all you do is ride road, you don't need it. But just because it's suspension does NOT mean it squishes and bounces with every motion. THAT'S what you get with the crap at Wal-Mart, not a real setup.
Front suspension changes bumps in your path from punches to pushes. Rear suspension does that for your spine, front for your arms and chest.
I swear, some of you are as bad as drivers about our road rights....
