Bikes do not get more original than this! Original owner, original paint and original components. After a 500 mile round trip, SB1861 is on the workbench.
SB1861 dates to late 1977/early 1978 (there will be more on the date in the next post); it is built from Reynolds 531 Double Butted tubing with all the features you would expect for this era 531 SBDU Ilkeston frame. Original frames like this are so important for confirming paint and features on my SBDU timeline.
