Thanks for the link....although the seat post was only $9.99 shipping would have been $26.20
So in the end I went Withoutdoors.co.uk
and got me one of these from BBB bike parts
Cost just over Â£20 inc p&p and it's the twin screw system, where as the others I found are single screw...it's a bit nore, but it comes from the UK, I don't have to pay Â£13 to get here and run the risk of Mr Tax man coming knocking
FYI I also found that Selcof
make one and it's available here
slightly cheaper single bolt model
OK, OK I know they aren't retro, but I think I'd have more chance finding a chicken's dentist in full time employment, than a decent 26.0mm black seat post from 1989!
1990 Kona Fire Mountain, when I can lift it!
1994 ish Marin Pine Mountain - slicked up commuter
1994 Kona Kula...nice
