Possibly a CAAD12 Disc, Dura Ace, with Hunt carbon wheelset
Not marketed as an endurance bike I know, but it's comfortable for me, especially with 30mm tubeless tyres on the Hunts.
I normally ride a 54 but the CAAD12's size up on the large side so I replaced my 54 with a 52. I'm 5'10".
Also in SE London (Greenwich)
Will get an actual pic, but this (with the much upgraded wheelset)
