A Mavic 27.2 seatpost sold on eBay last week with a Buy it Now for $75. I should have bought it...but I didn't like the price for a short post.

It wasn't the 350mm Mavic post but the 200something. Therefore I could only have used it on my Mavicish BOBish touring bike, not on my 'tout Mavic' road bike build. There really was no good reason to have a Mavic post on my touring bike. It already has a perfectly good American Classic post, and I have a titanium American Classic back up post. I didn't need to go three deep on the seatpost roster for a bike that I couldn't use the seatposts on any others I have.

The touring BOBish bike ('86 Cannondale ST800) is 7cm larger than the 'tout Mavic' road bike. So I definitely needed a 350mm for the All Mavic build. I don't think I'll ever find a Cannondale road frame bigger than 66cm so I need the long post. Though a couple exist (either customs or whatever). I saw a 68cm get snatched up really quick on the Serotta forum.
