Talk to the owner and find out what kind of rider (s)he is. If they say anything about racing or being a club rider, I think I'll pass cause chances are pretty good that its got miles on it.

If on the other hand, the person was going to be using it for their exercise and decided it wasn't worth it, then you probably have a really good deal. If it was stored properly and have collected bit of dust, its probably more than worth it.

I think there are ton of good deals out there. Especially bikes in smaller frame size 52cm and lower. Same with trainers and other athletic equipment. Just see the owner and gauge their level of activity.

oh only time I bought anything from another racer was a SRAM groupo brand new. It wasn't used so I didn't mind that the owner was a cat 2 rider.
