Anyone sitting on an unused round saddle clamp (four pieces, two bolts) for the super-deep aero seat post that was used on the Cervelo P and maybe S series around '05-'13 (seat post has two round cut-outs, saddle clamp fits in one depending on how far forward or back you want to sit, there's a two-piece screw-together blank to fill in the hole that isn't holding the saddle clamp)? If so, maybe drop me a PM if you'd be willing to sell?
Thanks!
