I received a Racing Zero Night (high-performance wheel set) from a customer for repair.

They said the spoke is bent and the wheel has runout.


↑It's bent.
This is shot from the non-drive side, but
from the wheel's forward rotation direction, the impact mark is actually opposite to what you'd see from spoke wrap.
I really want to write about this in detail someday, but
it was caused by hitting a metal stag beetle (large insect) in the Yodogawa River.


Fixed.


↑Replaced spoke


The low side sprocket with wide-range tooth count is
something the customer assembled themselves, not the stock tooth count.
