Hi
Wonder if anyone has any suggestions?
I put a oneup 42t Cassette expander on my bike with a radr cage on my rear derailleur and also an oval chairing on the front.
My problem is I have now went through 2 rear derailleurs that have on (the lowest gear) caught on the cassette and snapped.
Both times my bike has been tuned by a good mechanic and the gears have been shifting excellent on the flat. the bike seems great on the flat to the trail until I start climbing.
The strange thing is that when I go to a slight uphill is when the lowest gear catches and breaks the rear derailleur.
All the drive train parts are practically new and the chain length seems to be an OK length?
My bikes a nukeproof mega 2012
Thanks in advance.
