My deraileur orbea onna’s deraileur keeps abloutely exploding, even tho it has been fixen in orbea dealer 3 times

4th times a charm.. lol just buy a different one

While Tourney isn’t known for sturdiness, i can’t help to think WTF when i see the dangled cage. Did you hit a rock and it got into the spokes? No derailleur would have survived that.

What did you do to it?

There are just some riders who can wreck everything. Maybe you are one of them and should ask your LBS if he knows any bike brand that does product testing. That would be the perfect job, testriding and finding out how parts fail.

Or maybe you really do extreme mountainbiking and a derailleur isn’t doing it for ya. Get a Pinion or just ride singlespeed then.
