I bought all of this in July 1991 when I ordered a custom Chas Roberts DOGS BOLX.
As was the mode at the time, I upgraded/swapped out most parts for purple spangly bits whilst continuing to use some of this stuff... most of it has been in my spare parts boxes for the last 16 years(!) Some of these parts show more wear than others but ALL OF IT is in very good, useable condition. The wheels are straight and true, bearings very good and braking surfaces flat. The chainrings have plenty of life left in them (the granny and middle ring both being steel replacements anyway). The thumbshifters work flawlessly, brake levers are in nice condition, cassette is not that used, etc..
Would prefer to sell as a whole but willing to sell individual items... discount for the whole lot at Â£120 posted.
