Come on Elton - i just had a look at the re listing :
wash and wax the “stealth black frame”
Buy a tube of “Autosol” and give metal work a polish
get rid of rack
leave mudguards as the bike is “ready for the winter training sessions”
possibly fresh bar tape
that “ classic British Brooks saddle” still has enough life in it to “ mould itself to the lucky new owners anatomy” - it is certainly not uncomfortable
What is your inside leg measurement/height, as you have ridden the bike for 100’s (1000’s ?) of miles and a person of similar stature would find it a “supremely comfortable steed”
£100 is not too much
