Just wondering whats available these days for off-road tandeming. I've looked at the MTBtandems.com site, so I've seen all of those. Are there any others available, or any other choices?
There are some older Cannondale MOTO FR's around, but there are no rebuild parts available.
I also have a question about axle-crown heights, and offsets. Is there a common spec for either one, or do you just not worry about this on an offroad tandem?
