Looning for new BB and see that there are std and E type ones available, need a 73mm / 121 accoprding to label on existing, but how do I know if it should be an E type?
ta
E type ones are for BB mounted front mechs
Unless you have a funny shape full suss you probably don't need an E type
You only need an E type if you have an E type front mech. E type mechs attach to the BB rather than the frame. So if your front mech is attached to the seat tube you need a standard BB. IIRC you can't use an etype bb without the mech unless you have some sort of spacer.
cheers and thanks for that info, never knew such front mechs existed.....
I have an E type on my SS and no front mech (obviously as its an SS). No problems what so ever. I think most XT BBs were E type.
