>>1201710>>1201721You def. need a new bottom bracket.
First measure the lenght of pic related, not measuring the threaded part.
it's gonna be anywhere from 116 to 127mm.
Then find out if you have a BSA or italian(rare) threaded frame.
You can check by reading this article.

Good luck
Oh and grease the threads before installation.
