Campagnola 26.8 Aero seatpost_Nutz?
I saw the listing on CL and thought hmmm, that fits my '88 Schwinn but then saw the price of $220.
It's polished which to me means he might have done easy off first.
Is this price crazy?
Nuts. That's a Campagnolo Triomphe/Victory seatpost. $50 max - and usually less, these posts are generally the best value out there for Campag aero seatposts.
I'd be rather surprised if a genuine C-Record post brought that much unless NOS in box.
If you are looking for a good seatpost, check out eBay for a Suntour XC Pro, or Superbe if you want the shorter road version. The XC Pro has the best seat adjustment I've found, I think it is called micro adjust, you can literally move the nose up or down by fractions of a mm. I bought one as new for about $25. They are long ~ 300 mm, but light enough and nicely finished. If you don't like it that long you can always cut it shorter.
