Hi, can anyone help I have a Specialized hardrock sport 8speed. The bb I have has splines each end of the spindle (I don't know what model it is). Ideally would like to upgrade but don't want to have to change my gear setup, does anyone have any recommendations I was thinking shimano deore 2 piece external bb but have a feeling they only come in 9spd arrangement. Thanks for any help!
