I received a rear wheel from a Racing 1 bike from a customer.

The rear derailleur got caught up in the spokes.

First, the spoke on the porcupine side was gouged and deformed.
Based on the severity, this was the initial impact.
The damage on the porcupine side suggests
the derailleur got caught on the hub side of the final cross point.


On the opposite side of the initial impact point,
two consecutive spokes on the anti-porcupine side were deformed.
These are bent at a position closer to the rim than the final cross point.


I replaced them.
