2015 model Campagnolo Zonda Wheelset Full Ultegra groupset a few faults that I am sure for someone in the know would be able to easily sort out there is a loose/broken spoke on the rear wheel which means the rear wheel doesn't spin true the drivetrain would best to be replaced, the front cogs are the original and have done over 10000 miles, the rear cogs and chain have been replaced over the years but I'd imagine it would be best with a complete new set. derailleurs should be fine but im not an expert any q's please feel free to drop me a message collection only
