    Bottom Bracket Replacement Help!

    Hey all. I have a Scott Voltage FR 30 -2013. The stock BB is a Howitzer 73 GXP on it. HOWEVER, there is a killer deal on a Truvativ Descendant GXP 83mm crank/bb. I can't really find if changing shells is an option or if I need to stick with the 68/73bb. Helps! Thanks!

    You have to stick with what the bike frame is made for. If it's a 73mm bb, then you can't put an 83mm crank on it. Ttyl, Fahn

    What's wrong with your current bottom bracket that warrants replacement?
