Hello to all bike mechanics!
This 13 year old road bike was fitted with Shimano Ultegra 10 speed cranksets.
After so many years, the bicycle connecting rods have worn out. It is no longer possible to find parts for Shimano Ultegra cranks at 10 speeds. We were forced to replace the bicycle connecting rods with more modern ones, but of a lower level.
This is a Shimano Tiagra level bicycle crankset.
