Hi,
I have a Worksop built Frame and fork set (currently built up). It was bought NOS, about three years ago,with a few shop-soil scuffs. Full 531 (ie not just 'main tubes'). Good condition, built up and admired rather than ridden (has been ridden a few times, but less than 50 miles).
Classic red, yellow and black team colour scheme. Badged as a 'Record', but it was for the european market and has a french threaded bottom bracket (I have installed a new 'eccentric' bottom bracket (good quality, from Velo Orange).
Size - 60 cm ct, the top tube is 56cm and the head tube is 17cm. I'll take some pics if it may be of interest.
Price - frame and forks, with bb and headset, £200 posted? Happy to discuss.
Good luck,
David
