[citation][nom]dokiardo[/nom]Look at it. It isnt hard to tell how it works. The fram looks like one of those old jump ropes with the plastic dongels over the whole thing. Just pull the rope in the middle and tighten it, and bam all the plastic things will line up. But the problem is rigidity. If you look under his seat, he has a lever that he uses to tighten the line inside of the fram, or losen it. This allows it to bend around the pole when he releases the tension. I dont understand why I got knocked down for posting an obvious flaw in the bike.[/citation]I didn't knock you down but to me, coming to a conclusion on something like that is just a little premature. I am sure it isn't plastic. That would just be stupid.
