I used to live in Bath hence knowing Robin when he was starting out ~15 years ago - though it took me a while to get my act together and decide what I wanted. I’ve lost contact, I think he’s going through one of those phases of not building right now.
The Spectrum has a 60cm TT so I think it’s just the camera angle.
I’ve done more rummaging this evening and come up with the bars (3T Morphe), wheels (Chorus on Open Pro CD) and a chain and pedals (Time ATAC) for good measure.
I’ve also decided I might swap the PMP Ti post out for a Campagnolo Ti one.
So the missing piece is now a Moots Ti stem that I put somewhere for safe keeping and of course cannot locate....
