Bike Friday tandem - any cons?
I'm trying to convince my wife that we should buy a Bike Friday tandem now, while the NZ/US $ exchange rate is so favorable for us (even though we really won't need a second tandem for a couple of years). I'm sold and, despite trying, have had no bad comments about Bike Fridays. It seems that it will do everything we want; pack up for travelling, accommodate our children as they grow, allow me or my wife to captain, deal with the terrain that we want to ride on.
I think the only thing I have found that would be a con is the small wheels on trails, giving a bit of a rough ride (although our current tandem is aluminium and the BF steel will give a different ride feel anyway). Is there anything else I should be aware of with BF tandems? Also, does anyone have any practical experience with SRAM dual drive; it seems like a good solution, but what are the downsides?
Cheers
