New bike arrived with rear derailleur cage tilted, bent hanger or incorrect installation?
The rear wheel, chain and derailleur arrived preassembled, and I have not ridden the bike yet.
Viewed from directly behind, the rear derailleur cage and its two jockey wheels do not appear parallel to the rear wheel. The chain is being pulled sideways, does not track correctly through the upper jockey wheel area and will not remain properly on the smallest rear sprocket. When shifting inward, the derailleur also gets dangerously close to the spokes.
For full disclosure, while troubleshooting I tightened the L-limit screw fully clockwise and then backed it out again, so the limit screws will need to be reset. I have not removed or loosened the main mounting bolt, and I will not ride the bike in this condition.
Can you tell from these photos whether the derailleur or hanger is bent, or whether it has simply been mounted incorrectly? Should I attempt to reinstall it, or return the new bike under warranty?
