Bought in August 2017 direct from Thorn as a bare frame, built up with the detailed spec below, including Shimano Di2 electronic gears. The S&S couplings mean the frame can be separated and boxed small enough to avoid extra airline charges.
The bike is in excellent condition and used only for one tour of 1,220 km in Thailand in 2018, and another of 809 km in France in 2019. It had less than 100 miles of bedding-in rides in the UK, in dry weather only.
Electronic gears were chosen to take pressure off my arthritic thumbs and worked superbly but as my arthritis has progressed I’ve been unable to ride it more recently.
Can be fitted with straight, curved or drop handlebars to suit the buyer.
PRICE: £1,950 ovno plus delivery (collection also possible) One pic below but many more available on request! Contact:

The frame size is 475M for 52cm forks, reckoned by Thorn to be suitable for men or women from 1.49 to 1.57 m tall in bare feet (4'11" to 5'2"). BUT Thorn also recommended it for my 5ft 4in height, as I have slightly shorter than average legs. The 'stand-over height' is approx. 71.5cm (2'4"). If you can get to the Edinburgh or Kinross areas, you can have a trial fit on an indoor trainer and/or a trial ride.
The frame is Thorn 969 double-butted, seamless, heat-treated, cold-drawn, Cro-Mo steel, with not a chip or other mark on the paintwork anywhere, even underneath the bottom bracket, chainstay. The blue paint on either side of the top tube is very faintly yellowed and so is barely visible in the photos, however it’s only fair to mention it here.
COLLECTION / DELIVERY: if you cannot collect the bike, it will be sent by a courier service. In that case the bike will be supplied partly dismantled in a bike box (wheels off, pedals off, handlebar twisted round, or off, etc) If you live within about 100 miles or so of Edinburgh, we will be happy to deliver it, fully built-up, for cost of fuel only.
* Security: as this is a valuable bike, it has a hidden, non-removable RFI 'Immobitag' which means if lost or stolen, police can trace its registered owner - registration will be transferred free of charge to the new owner. If sent by courier, a tracker will also be placed in the box.
