Looking for a 68mm x 116mm Bottom Bracket for E-Type Derailleur
I'm rebuilding a Trek 820 from the late 90's and am in need of a 68mm x 116mm Bottom Bracket compatible with an E-type front derailleur. The one I pulled out is marked "BB-CT91", "68" "UG", "BC 1.37 x 24", "YL 116".
From my research, my understanding is that the correct bottom bracket should have an "E" in the model number, denoting that it is compatible for use with an E-Type FD.
Any suggestions as to where I might find one? ... I've tried all the normal on-line sources, and don't believe I've found what I need.
Any help would be much appreciated.
