Trek or Cannondale?
We love our Trek 1000, did our first 40 miles for 2007 today in a wonderful January day in NC.
Put 2000+ miles on it from March of 2006 to now and have had no problems that the dealer didn't promptly handle.
Have some friends in our club that have Cannondales and they will swear by them but you probably won't go wrong with either.
Enjoy your new tandem!!
