If anyone in Aus is interested in a dual seat that won't take a backrest, let me know. It's almost brand new; only used for a few weeks and now very occasionally. Straight after I got it I saw a member on here selling his bike with the backrest model and made him an offer on it - the seat that is. Once I got used to the idea of the backrest, it's the only one I use. Happy to hang onto both as it's a bit of a fiddle getting the backrest off and once in a while I like to go without (it only takes a second to swap seats) but I'd be prepared to part with it.
