I was wondering if you could help me, i'm putting together a custom Top fuel 9.9 and instead of the Shimano XTR i want to go with the Sram XX Groupset.
I have a 19.5" Top Fuel 9.9 SSL 2011 Frameset and was wondering which Sram XX crankset/BB combination would best go with this frame?
Plus what is meant by "164mm Q factor" and "156mm Q factor" when talking about the BB30 cranksets?
Of course this is all assuming that the frame is compatible with these BB's, Please correct me if i'm wrong.
Thanks in advance for your help
