Background: I bought this used frame and came with BB setup like this. Seller didnīt mention any problem with BB, but since I really wanna have Shimano groupset, I need to go this way so I can fit 24mm spindle of crank.
Any thoughts?
I dont think that is going to work.It appears to be designed for a standard BB30 frame, which would have a 42mm interior diameter shell. Your PF30 frame has a 46mm shell to accommodate the pf30 cups. To use a converter like that, you have to bang out the cups and, as [MENTION=179963]cpach[/MENTION] says, get one specifically designed for pf30-24mm conversions.
