I can't read the logos, but the bike looks like a Ti frame. It certainly has a good headset....I wonder if the "owner" knows the make of the headset........I wonder if the OP knows where he was when he took it? I have a good idea.
We were in the UK when the photo was taken. Outside of Ebrington Arms in Gloucestershire if my memory serves me right. Beautiful B&B. The headset is from King and the stem from 3T I think. Again, I don't know a ton about bikes and I don't have the bike with me. Out of town until the 1st.
