I have a KH double crown which I few year ago briefly used for pairs - for which the 2nd crown is perfect.
After I start using it, I already soon stopped using it; simply because I got my Nimbus ti.
I never abused it, always was careful on it, and so it has barely any traces of use, and certainly is guaranteed to be perfectly straight.
May go against any reasonable bid.
Oh; comes without displayed seatpost clamp.
