I have just listed our two vintage Saracen Sherpa ATB/Mountain bikes on Ebay. These are very similar models to the ones that Nick and Richard Crane took up Kilimanjaro in the early 1980's: https://www.amazon.co.uk/Bicycles-Up-Ki ... 0946609497.
For details of the bikes for sale search Ebay for title "Vintage 1983 Saracen Mountain Bike".
