I have a 1991 Series 70 pdg. Great bike. I paid $250 on CL, which was a bit of a stretch, because it fit me perfectly. Here's a (mislabled) 1992. It's a great bike too. But $800? Dream on. Perhaps it would be worth $800 if it actually were titanium, as the seller claims. Let's hope some poor sucker doesn't buy that and purchase.
