Hi All

I have found out the following informatin about my bike after a lot of searching.

External diameter is 46mm

Intrnal diameter is 30mm

and width as i know is 73mm.


I would like to install a mid drive BB02 kit but unsure where i would find the bottom bracket adapter and the correct size .


Can anyone point me in the right direction please?
