Hello. I have a 2006 Raleigh Grand Prix, and its bottom bracket and crank set are pretty worn out. On the catalog it says that the BB is Truvativ Power Spline Cartridge, but I cannot find any other information concerning the size of BB. Is there a standard that most road bikes follow? I measured that the shell width of the bike is 68mm. So, can I just bike a crank set that comes with a BB for 68/73? Also, if the original crank set on the bike is a triple(52/42/30), do I need to do anything if I want to upgrade to a 52/39 double?
The website of crank set that I was thinking of buying is : http://www.jensonusa.com/Cranksets/S...00-Crankset-Oe.
Thanks for the help.
