Big Bottom Bracket
I have question about shimano 105 5800. Im having problem installing the SM-BBR60 bottom bracket in my mosso frame. It seems too big. Does SM-BBR60 comes in different thread size?is there smaller than 1.37 that will fit in my 105 5800series?any suggestion?I don't want to change my bike frame and I want to use the 105. Can you please kindly help?
