I need advice on replacing an E-type bb on my Raleigh M-30.
I went to my local repair shop and they are saying that they are not able to order an E-type bb that matches my current set-up (68mm x 116mm, tapered square). They ordered a 73mm instead saying that that would compensate for the added width of the E-type derailer.
Quoted message said:
From what I have been reading this does not seem to be a true
statement and that the main difference between an E-type and a standard bb is the size of the flange (diameter) for holding the derailer in places and not width of the bb. Please help clear the mystery.
