I've made 3 of different lengths of elastomer and some plastic washers for preload adjustment. The bike is quite a bit further on than in the last photo so just a bit more fettling before I can test it out.
If I like it then I can see it getting some serious TLC in the paintwork department, if I hate it then I'm going to strip it and use the bits for something a bit more conventional.
Stick around and keep us up to date with your progress, would be happy to help out with elastomers as long as they work ok.
