I bought XTR - fitted today... The Shimano switch was planned at some point. Now just slightly accelerated. I now only have the wheels & cranks left of the original bike!
Well it's gone in under warranty. The weld has let go, which caused a catastrophic loss of chain tension. The cage was eaten by the cassette so all bent. You can see the thread is still on the bolt.
No reason for it to happen other than a defect. I simply shifted up a gear whilst cycling down a nice gradient and it ended like this... Jockey is MIA in the bush. We'll see what SRAM come back with.
