just helping seller out with some info and images:
There is a choice between frame only (with fitted headset and seatpost) or the complete bile as shown in the pics, but with a Shimano Ultegra crankset with a new Shimano 105 53t single ring. The frame is unmarked and has been resprayed at Argos Cycles in Bristol. The complete bike option is £285.
I am based in Gloucestershire but could meet in Oxford if you are London based.
