I have a Cinelli 1A stem that may have been sanded down a bit to fit in a frnch bike. I am using it in an italian bike, and it moves a little. This is encouraging me not to pull on the bars when climbing, which is probably good for my form, but I would like to have the fit be tighter. Does anyone have any suggestions about shimming? Tin foil? Pop can?
Best regards,
