A couple of responses; from 2010
We have a Twinspinner tandem which we bought on
ebay recently. We enjoy riding the tandem far more than riding two solo bikes. Steel frame, HEAVY AS! Suntour 3 speed internal hub gears with a Sturmey Archer stick shift. on the top bar. Gearing isn't low enough or high enough. Have tried to get it upgraded with modern gears and local shops start out all enthusiastic then gradually it becomes all to difficult to not economically viable to "it's a classic! leave it as it is." Has 26 x 1 1/2inch tyres. Front tyre is cracked and bubbling but unable to obtain new tyre in South East Queensland. At this stage it looks like we might have to import them from the US.
www.sheldonbrown.com sells them. I think we will be getting a nice shiny alloy framed modern tandem for Christmas!
My Twin Spinner also had Sturmy Archer gears, but fortunately I managed to convert it to a 5 speed external cassette. It rides really well except it is quite whippy if the riders aren't in harmony.
