Bicycle question: Trek 7000 vs 7200?

You don't need shocks on paved surfaces, the 7000 has a suspension seat post that will smooth most small bumps out. If you ride bike trails that are rough get the 7200 with shocks. If the 7000 rides a little rough you can always change the tire pressure or change to wider tires. I ride a hybrid without shocks on rail trails and the rough spots are a pain where the horses tear it up. The tires are 700 X 35 on the 7000 you could go to 700 X 40 if you have a problem. The shocks on the 7200 have a preload adjustment and only 50mm movement so it wouldn't be too bad on hills.
