Carbonfiberboy, can you elaborate on your statement: "I think belt alignment is easy on a tandem, at least it is if you use cranksets that the system is design to work with." with respect to appropriate cranksets? I've looked through the Gates website and manuals and didn't find any specific recommendations for cranksets other than to BCD size and ring size (130 BCD spider for the 69 tooth tandem rings). It would make sense that a bottom bracket format which allows relatively easy chainline adjustment would be most appropriate. The options I'm looking at right now would be an FSA crankset with MegaExo BBs or a DaVinci crankset with JIS sq. taper BBs. Of the two BBs I think the MegaExo is the more readily adjusted in my limited experience. Your thoughts?
