We bought a Bob Jackson tandem 4 years ago.It was lingering in the guys garage we bought it from for 10 years or so and was a bit of wreck but we paid 400 quid for it as we were told it was worth it just for the frame alone as it was a Bob Jackson...Anyway we sent it off to Bob Jacksons in Leeds for respray and our LBS did a fab job putting it back together with sti gearing new tyres mudguards pedals etc and had looking like new..It is now lurking in our garage doing nowt but i'm loathe to sell it but am curious about its value...anyone know the price of good conditioned tandems? just curious
