One of my sons, who is pretty big and strong,, rides an S-Works Tarmac CF frame (about a 2006 model or so) with the plastic (polymer??) bits in the forks and the chainstays. It seems to be in excellent condition. Have you ever heard of any problems with the plastic suspension bits disintegrating or breaking after a long time? Thanks!

Zerts? I didn't think those were used on the Tarmac -- just the Roubaix, Ruby and Diverge. After 13 years, I would think the Zerts are inert. I couldn't imagine how they would fall out.
