I have completed restoration of Raleigh SBDU SB576. This is a very early (believed to be the first) Reynolds 753 time trial special built for the general public and was delivered in February 1976. It was regularily used in tt competition in the UK through the mid 1980s. Purchased on eBay (UK) last October as a restored frameset, it has been built up with some of the lightest period correct components of the era to achieve a weight of just 17.6 lbs.
