Today my rear derailleur has got caucht up on the spokes of my back wheel and snapped clean off on the way down a rocky hill.
I'm wondering if I need an apaptor for my bike for a new derailleur as one of my mates told me I'd need one?? My bike is a Specialized Hardrock Pro and the derailleur is Shimano Alivio.
Also what would be a good upgrade from this derailleur?
Hope someone can help,
