Good afternoon all! In previous questions, I've mentioned that I intend to rebuild my 2000 Trek 7700 Multitrack. Well, I'm beginning by replacing the bottom bracket. According to the spec sheet I got from Vintage-Trek.com, the BB is Shimano BB-LP27 73x113. I've searched for BB-LP27 73x113 and come up empty. I assumed this is an obsolete part, but there must be a current part which will serve the same purpose. How do I decipher what current part would work in this application?
I'm adding the technical sheet I found on vintage-trek.com.
