That will fit both 68mm and 73mm width BBs, you just use spacers which it will come with if you have a 68mm. You will also need a Parktool bbt-9 bb tool that pops up in the "frequently bought together" section to install it. You will also need a crank puller and different BB tool for your current crank and BB. The parktool BBT-22 and CCP-22C or the cheaper alternatives.
