I've just bought a Super Galaxy Twin in startingly good condition. It's been modded a bit a previous owner, in that the drag brake is now operated by a lever on the stoker bars. I did this selfsame mod to the same model bike many years ago. Looking at this one I think the reaction arm is put together wrongly. From the outside it goes bolt head, cable stop bracket, chainstay brazeon, reaction arm, bolt. The cable stop bracket has a wee tab which doesn't quite engage on the reaction arm but should. It looks like I csn either bend the tab or move the reaction arm so it's outboard of the chainstay brazeon. Has anyone else got this set up? Google image search is proving fruitless.
