In reply to phizz4:
Thanks for the ideas. I am selling the Saracen, not the Marin. I have just donated an old, steel framed, Dawes, to 'Bikes for Africa'
http://www.re-cycle.org/donate/bike/location-search
but was hoping to recoup some of my costs (both bikes were built from scratch, even the wheels, by me). I may strip the Saracen down and sell the components, but no one wants 'old but good bits'. The Dawes had 7 speed XT thumbshifters, which were the business a few years ago but, like computer technology, times have moved on. I find the same thing when trying to sell old outdoor kit- no one wanted my Karrimor Alpinist fleece, probably because it doesn't say Patagucci or Arcterex on it.
