We are about to go on vacation. DH thought it would be fun to try a tandem. I certainly agree, but I have some questions. Because of the size differential, (Dan is 6 ft, I'm 5 ft) I assume he will have to captain, but I am the more experienced and stronger rider. I would really appreciate any tips on basic tandem technique; starting, synchronizing pedaling, stopping, shifting, dismounting, etc. I expect this to be a 24 speed Trek T900.
