Craig Calfee can upgrade with BTCs, mounts for discs. The brifters can be upgraded to 10spd, and I can get new wheels, but I'll try selling it as is initially. If it doesn't sell, I may just give it to a friend or relative that is interested in tandem cycling. My neighbor across the street is dying for he and his wife to take it for a ride. I'm at risk with this crap going around, so I can't get close to others, so instructions for them will have to wait.
Thanks for the input.
