I have a Dunlop doubledisc26 Mountain bike. Recently i was cycling down the road when my derailleur fell off suddenly. The derailleur was on a bolt which is screwed to the frame. When i looked there is nothing on the end of the bolt to keep the derailleur on. I am guessing i need a new bolt with a nut or something similar on the end, but i can't find one. The derailleur says 'Power index system' but i can't find any information anywhere which could point me where to buy a new derailleur bolt. In fact, i can't anything at all on who made the derailleur.
I am unsure of where I can go with this now and would really appreciate some help. Someone suggested i just see if a shimano derailleur would be compatible but i need one which has a bolt the same thread size to screw back into the frame again. Possibly one which can go straight onto the wheel bolt?
Sorry if i haven't described my situation very well, but any suggestions/advice would be great, thanks!
