Thank you I am unable to find out much about Dave Yates tandems and why they are so specialThat frame is right in all respects (as you'd expect from Dave). It seems in good condition too. It's not a huge market, so it depends very much on who's interested. I'd say £700-£900 would be a good starting offer.
I'd probably want to change to bar-end levers, though it looks as though it has one on the left to operate the drum-brake, so that would have to go elsewhere. But it looks perfectly rideable as it it.
