Thank you very much, I have owned this AB Champion Mondial from new, it confirms its a 1985 model originally in ivory, with the full 600ex groupset, it was repainted and had a front changer lug added during 1988.
It has been lofted for 5 years, now I plan to clean it up, and post some pictures in the near future.
It was raced by me as a 2nd cat and has been ridden in France, Belgium, Spain many times.
Can't thank you enogh for the help so far.
Thank You.
