Well obviously I could do it in 180 odd if I had an aluminium frame, but mine is steel, so I have to keep stopping at cafés and bars etc.... And I have to wait for the woman, she steadfastly refuses to cycle any faster than comfortable dawdle. My ale gut makes aero position impossible, so I'd have to wait for tail winds and I can't read maps, so Guinness would probably disqualify me for taking a short cut or something.
I think the Signatures are stock frames with finish and components of choice. Bikefix have a thing to play on.
It's possible his one is unique, though I can't think why they'd have used a chain tensioner on a Rohloff if that were the case.
But what a ride, I've been folowing it for the last couple of months. I wonder how long that record will stand.
