Nice. I’d like an Orbit at some point, I bought one unseen ages ago that had been shaved clean of all cablestops for a singlespeed so was a non starter.
That seatpost has the look of one that’s either checked as free and dropped down or is at the position of maximum grief!
I've always fancied an Orbit, but no room for one at the moment. I should be able to help with collection if required. Or even better, you might be able to get someone else attending York Cycle Show to bring it closer to home for you.
