removing frozen Cinelli 1 A stem
My neighbor has his daughters bike a Trek ( aluminum frame early 90's vintage ) and the Cinelli 1-A stem is frozen in place... I am trying to help him remove it so he can put a shorter stem on it.
I have no idea if the steering tube is alumnum or steel. other than drilling it out has any one come up with a good chemical to cut the aluminum corrosion that causes this...??
