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.
Thnx for the replay. I'm actually thinking of bidding on this one here
FSA GRAVITY GRID crankset 175mm including BB | eBay
It says it supports both 68 and 73mm. One of the reasons i was concerned is cos I thought that those numbers show the diameter of the threads and it wouldnt fit but now I'm believing it has to do with the length of the BB (or am I still wrong)?
Im not interested in tools to change it as I'll go into a local shop to change it. I'm looking to pick one that fits to buy.
