Ok sorry about confusing you with all the incorrect sizes i gave you but, i guess my question is how do i fix a pinched stem. I bought the stem off of someone a while back and it must of been over tightened or tightened too much. I know a few of you answered on how to fix it but im still a little confused. I took the back bolts out but what do i need to do and could you be pretty specific. I have no shops around me

It's pinched
Take the back bolts out
Put them in the other side of the holes that they usually go in
Thrn thread them in until the head of the bolt is close to the other side of the stem.
Put a coin in between the bolt and the stem on both and tighten a 1/4 turn at a time until it slips off

this question makes no sense, the 1 & 1/8" refers to the steerer tube, the 3/8" refers to the dropout size.

Just hammer it off with a rubber mallet

This would work. Another tip is keep the bars on your stem when trying to get the stem off for leverage.

The coin method is always your first choice. But sometimes, some stems won't have the bolt hole threaded to be able to thread in the bolt from the outer side. If all fails, then use a screwdriver and pry it, which causes damage, obviously. But hey, better than having a permanently stuck stem.

Will the coin method actually "un-pinch" it or will you need to use the coin everytime you decide to take off, put on or rotate the stem?
