After search craigslist, ebay and tandem classifieds since March, we finally found our tandem. It is an older Ibis that was right here in Portland, Oregon. The previous owner converted it from a mountain to a roadie. Now I am going to covert it back. Strange, it has two rear brake mounts. One has been removed. I would like to control both rear brakes with one lever.....? This is my first challenge.
